10 COMMISSIONING AND TESTING
Commissioning
Please see manual for control system for proposed commissioning
procedure.
Testing
While the lamp is monitored also in standby mode, the lamp must be
switched on to test all parameters. The lamp should be tested at suit-
able intervals. This can either be done by manually switch on the lamp
or using the test function described below. This test function is de-
signed to be used for automatic testing and light intensity during this
test sequence will not become a hazard for helicopter pilot or other
personnel.
Procedure, test function:
1. When in standby mode and “dim” signal is off, set “sync” signal
(digital input) to ‘1’ for minimum 2 seconds.

9 PUTTING INTO SERVICE
The lamp is designed to receive a defined set of inputs from a special-
ized control system and return a set of values in terms of faults and
alarms. We therefore strongly recommend installation of the TEF9980
only together with Tranberg control systems. The safety of the product
is not based on the control system. Testing of the light and control
system after installation is recommended.
Before putting into service:
1. Make sure that the device is not damaged.
2. Make sure that the device is installed correctly.
3. Remove any foreign objects from the device.
4. Check the tightening torques.
