7.5.6.2
TEST mode
Set the Mode switch at the CPSU successively in the Test and Auto mode.
Measure the DC-voltage via M31 related to M8 (0V).
Mode switch
M31
Test mode
> 4.0V (TEST is activated)
Override mode
< 0.5V (TEST is inactive)
7.5.7
Internal signals only for Delegate Units
•
See also chapter 7.1 and 7.2 for explanation of the signal modes.
7.5.7.1
Override Mode (ORM)
Set the Mode switch of the CPSU successively in the Test and Override mode.
Measure the DC-voltage via M35 related to M2 (GND).
Mode switch
M35
Test mode
> 4.0V (ORM is activated)
Override mode
< 0.5V (ORM is inactive)
Set the Mode switch of the CPSU in the Override mode
Press the microphone button and measure the DC-voltage via M5 related to M2 (GND).
Detect the presence of a voltage pulse > 13.0V (after the pulse of 5.7V).
7.5.7.2
Maximum number (1,2,3 or 4) of Delegate units that can be activated at the same time (MAXNOM).
Connect at least two Delegate units to the CPSU.
•
Set the Mode switch at the CPSU in the Auto-1 mode.
•
Measure the DC-voltage via M36 related to M2 (GND).
•
Activate one Delegate unit by pressing the microphone button.
•
Measure the DC-voltage again via M36 related to M2 (GND). MAXNOM should now be activated.
•
Try to activate the second Delegate unit. This may not be possible.
