MBJ CTR-51 Controller Instruction Manual

MBJ CTR-51 Controller

Mechanical Integration

The CTR controllers are supplied with plug-contacts for the LED light, control signals, RS232 interface and input power. The controller is made for top hat rail mounting, a clip locks the unit to the top hat rail.

Safety Notes

Before working with this unit, read the warning and application instruc-tions carefully and completely.

1. The device is designed for indoor use only.
2. Health – The device must be disconnected from the power source before the installation and/or maintenance can start. The device must not be used when a failure may cause a personal injury.
3. Electricity – The housing is electrically isolated from the ground of the power supply. Exceeding the permissible operating voltage or exceeding the maximum allowed switching current per channel can lead to the destruction of the device or to a significant shortening of the lifetime of the connected LED lighting module.
4. Mechanical integration – The controller is made for top hat rail mounting. A clip can be used to lock the unit to the top hat rail. For optimal heat flow a left/right distance of 10mm to next unit is recommended.

1. Dimmer switched off by factory default. Needs to be enabled via RS232. Without con-nection to pin 3, when dimmer is activated, intensity is like 0V = 0% of selected current
2. Longer flash times can be set via RS232
3. Input voltages above 5.5V will destroy the trigger input circuit!
4. for MBJ connecting cable and MBJ LED light (-x) without integrated controller
5. Do NOT connect to the external ground of the power supply or the ground of the trigger signal! This might destroy connected lights or devices.

Operating mode

Mode      CTR-50 Function                     Mode      CTR-51 Function

STEADY| Continuous light, LED always on| –| no support for continuous

light, use CTR-50

AUTO1)| LED-output follows the trigger| AUTO| LED-output follows the trigger
FLASH| Manual set-up for flash, delay

and duration (via RS232 only)

| FLASH2)| Flash-on-trigger with set flash duration (RS232)
OFF| LED outputs switched off| OFF| LED outputs switched off

1. The CTR-50 factory setting of the operation mode is AUTO. Other operating modes are selectable via the RS232 interface.
2. The CTR-51 factory setting of the operation mode is FLASH. Other operating modes are selectable via the RS232 interface.

Detection of the light source
After the CTR is supplied with voltage, it remains in Detect Mode until an illu-mination has been detected. Then the CTR changes to the selected mode.

Application Samples for CTR controller

Steady light

Steady light with brightness control (CTR-50 only)

RS232
The serial interface allows changing the operation mode and setup of individ- ual timings and currents. The control commands are described in a separate RS232 manual.
Rotary Switches
Use the rotary switches to set-up the allowed current for the connected LED. Please check the LED light manufacturer’s manual to make sure not to exceed the maximum LED current.

1. LED current less than 100mA may cause LED light jitter
2. The flash energy is provided by a capacitor and requires sufficient time for recharging. The flash energy (flash frequency flash duration current) is limited to 1A. E.g.: 100 flashes/s 100µs 30A = 0.3A
3. The higher the current and the shorter the cycle time, the greater the latency can be.
