Control Units

BB

Q What are the response characteristics of the PD2, CC-ST-1024, BB, PTU2, PSB-EX, and PJ Series (time lag between light turning ON after it has received an ON signal)?

A

The total output power, is the sum total of power being output at the same time on channel 1 and channel 2, and it can reach a maximum of 28W
(maximum power for each single channel also amounts to 28W).

QA No. 11-0100

Q Using the BB Series interface unit, is it possible to perform ON/OFF controlling via the input terminal?

A

We cannot guarantee that power restarting can be performed within less than 2 seconds.
Please perform ON/OFF controlling using the control terminal.

QA No. 11-0076

Q Can 2 interface units be used for 1 BB Series master unit and 7 or less slave units?

A

They cannot be used.
The 2nd connected interface unit cannot be used to control the Control Unit of the 8 or less units (1 master unit and 7 slave units or less).
Since each single slave interface unit will be allocated to channels 1 through 8, even if a 2nd interface unit is used, it would be necessary to add a 9th unit.

QA No. 11-0075

Q What is the time required to perform overwriting of dimming settings using external control for 2 channels from the BB Series interface unit?

A

After receiving the dimming settings write (WR) signal, a maximum of 30ms is required before the dimming settings are applied (as listed in the user manual).
Regarding the 2nd channel, since the signal cannot be processed within the maximum 30ms time frame mentioned above, the 2nd channel signal can only be processed after an amount of time equivalent or longer than the 30ms maximum after WR signal is first received.
As a result, in order for dimming settings application to be completed for the 2 channel signal, a minimum of (30ms+α) × 2 = 60ms is necessary.
The maximum time necessary for dimming settings to be applied is 37msec.

QA No. 11-0073

Q What factors can cause a "b error" for the BB Series?

A

The worst case scenario that can cause this is repeated disconnection of the master and slaves while power is being supplied.
For such cases, communication part damage has occurred, and it is likely that the master, slaves, or both will need to replaced.
Please contact one of our various sales offices.

QA No. 11-0072

Q What can be done to deal with the occurrence of a "b error" for the BB Series?

A

  1. Perform a hardware reset
  2. Perform the recovery command
  3. Check the ID configuration switches to make sure there are no duplicate IDs
  4. Check the terminating unit

If the above 4 steps have been performed and the system still doesn't recover, separate the individual units, and try to determine which individual unit is causing the issue.
Once the offending unit has been identified, please contact one of our various sales offices.

QA No. 11-0071

Q What is the response time between the trigger being engaged and voltage being output for the BB Series strobe type unit?

A

In the specifications it is listed at 3μs or less, and the actual measured performance is 1μs or less.

QA No. 11-0070

Q When using the BB Series interface unit (photo coupler input type), and performing ON/OFF control, if multiple light units are connected, how will this affect response time (time until light is emitted)?

A

Regardless of the channel order, there will be a maximum 32ms delay between each unit.
If 7 units are connected, the 7th unit will have a maximum delay of 224ms.

QA No. 11-0069

Q During PWM type usage of the BB Series master, when external dimming is performed from the interface unit, hardly any dimming change can be observed.

A

When performing trigger light-emitting, the only thing that can be externally controlled is the PWM duty cycle, and the width of the light-emitting interval cannot be controlled. In order to change light-emitting interval width configurations, the panel should be used for performing settings, and a copy command needs to be executed.
If settings are not performed, the default value of 0.1ms is read and used.

QA No. 11-0068

Q When using the BB Series interface unit, even when an external ON/OFF signal is sent, ON/OFF switching is not performed.

A

Using the master and slave unit options, please set interface unit ON/OFF switching to enabled.
(Since terminal block switching is set to enabled by default.)

QA No. 11-0067

Q We are currently using the PTU2 Series, but what would happen if we replace it with the BB Series?

A

If you are making use of the same number of units as the number of channels being used while also performing external control, you will need to acquire a separate interface unit.

QA No. 11-0066

Q How do we check the strobe light-emission timing when using a BB Series unit?

A

Light-emission timing can only be checked by inputting an external timing signal.
Please note, however, that it is possible to check light-emission interval width by checking the internal light-emission mode.

QA No. 11-0065

Q When using a BB Series unit, is it permissible to shut off power and disconnect the interface unit after external dimming data writing is complete?

A

The setting values that have been configured from the I/F unit are stored in each individual Control Unit.
However, since switching to EXT mode can only be performed from the I/F unit, if light-emission based on the stored setting values is necessary, an I/F unit must be used.

QA No. 11-0064

Q How can the BB Series unit be connected when using lighting that exceeds 30W?

A

It is not possible to connect lighting that consumes 30W or more to a single connector.

QA No. 11-0063

Q Is it possible to place a custom order for a BB Series unit that is supplied with a longer cable? Additionally, is it possible to replace the supplied cable with a robot cable?

A

In some cases, changes can be made to cable length and cable type as part of a custom order. Please inquire further with our sales representatives.

QA No. 11-0062

Q How should the BB Series unit be cleaned if it gets soiled?

A

Cleaning of units using volatile oils is prohibited.
When performing cleaning, please use industrial alcohol.

QA No. 11-0061

Q What is the BB Series unit's product design service life?

A

It is 4 years (projected capacitor service life).

QA No. 11-0060

Q How should a fan cable be connected when using the BB Series unit?

A

The unit is not equipped with a fan connector.
We ask that you provide a separate Control Unit to drive any fans.

QA No. 11-0059

Q For the BB Series strobe type unit, the interval during which trigger signal reception is disabled is listed as "x 17," making the interval longer than that listed for the PTU2. Is this understanding correct?

A

That is correct.
For the BB power supplies, the ratio of light-emission interval width to time during which trigger signal reception is disabled is 1:16.
For the PTU2, the ratio of light-emission interval width to time during which trigger signal reception is disabled is 1:14.2.

QA No. 11-0058

Q For BB Series PWM type units, we find that it is possible to connect and turn on lighting that consumes 30W or more, but at what point will the protection circuit activate?

A

Based on the specifications, the protection circuit is designed to activate when power consumption reaches 110% of the rated amount.
Please also note that there exists lighting that is listed as consuming 30W, but which does not consume 30W in actual use (due to rounding up).

QA No. 11-0055

Q When using the BB Series unit, although the manual states that pins 2 and 3 should be disconnected for the 6 pin connector on the light output-side, these pins appear to be connected when using the supplied cable. Will this cause any problems?

A

The reason that the supplied cable is connecting these open pins is simply to provide mechanical strength.
Since there is nothing electrically connected to the open pins, there is no problem.

QA No. 11-0054

Q When using the photo coupler type input for BB Series PWM type units, is it permissible to perform common grounding for the OFF (-) side terminals?

A

There is no problem in performing common grounding, however, from a noise prevention perspective, it is recommended that the (-) side grounding is performed independently for the individual terminals.

QA No. 11-0051

Q We are using a BB Series PWM type unit, and light is not being emitted when the unit is powered on.

A

The light is not turning on because the default dimming value is set to 0.
If the dimming value is changed, the light will turn on.

QA No. 11-0049

Q When using a BB Series unit, below what voltage level will the "Err6" low voltage error be displayed?

A

A "Err6" error will be triggered when the input voltage falls to roughly 16V.
When an "Err6" error occurs, the unit will turn off the light unit.

QA No. 11-0048

Q When using a BB Series unit, what are the conditions under which an "Err1" error will be displayed, and if this occurs, how will this affect Control Unit operation?

A

Although the "Err1" error indicates a short to ground, this condition will not occur at terminals or signal lines that are exposed to the user, such as the front-side terminals, etc.
This may occur for example in cases where a metallic part, etc., has entered the inside of the unit's chassis.
If an "Err1" error occurs, light units will automatically be turned off. In order to perform recovery, rectify the problem, and perform the key operations for the initialization procedure (if the same error occurs during initialization process, light units will be automatically turned off and an error will be displayed).

QA No. 11-0047

Q When using a BB Series unit, what will happen if an ID is changed while the main power is turned ON?

A

If IDs are changed during operation, subsequent normal operation cannot be guaranteed.
We ask that you do not change IDs during operation.

QA No. 11-0046

Q When using a BB Series unit, what is the principle behind light control (up/down) when using the ALL selection feature?

A

For example, if channel 1 (200) and channel 2 (50) is increased by 100%, this will result in a change of channel 1 (255) and channel 2 (100)
(although internally, channel 1 will be recognized as 400).
If this is then decreased by 10%, this will result in a change of channel 1 (255) and channel 2 (90), and a subsequent 90% decrease will result in channel 1 (200) and channel 2 (50).
If the ALL selection feature is enabled, the dimming values for the individual channels will be configured as follows:
For an arbitrary channel "y," the dimming value for channel "y" =
dimming value for channel "y" + dimming value for channel "y" x "percent value."

QA No. 11-0044

Q When using a BB-CPP-S interface unit, is it possible to control dimming and ON/OFF switching via parallel I/O from the PLC?

A

On a fundamental level, this is possible.
However, since the response time for the 1st channel is 37msec, and for the nth channel, 37 + (24 x (n-1))msec will be required, we recommend controlling it from the terminal block.
