Testing
Your AC receiver has an on board test procedure which steps through
outputs in the sequence shown in Table 1. The test push button is shown
in figure 1. The test takes 55 seconds.
Running the test procedure also allows your receiver to detect the
feedback polarities for your P/T head and lens.
WARNING : Your AC receiver PCB now contains live voltages
Using an appropriate tool, press the test push button.

Replacing the Lid
WARNING : Refit the lid securely to prevent unauthorised access
Tighten the four securing screws with an appropriate tool until they
cannot be undone by hand. Do not exceed a torque of 4 Nm.
Maintenance
Once your AC receiver is correctly installed and commissioned it
requires no routine maintenance.
Changing the Fuse
The fuse holder (see figure 1) contains a 10A A/S fuse for protecting the
relay outputs.
To replace the fuse, switch off all power to the module, turn the top anti-
clockwise using an appropriate tool, change the fuse and replace the top.
