Using T-GEN 50 with 4100ES,
Controlling a T-GEN 50
with a Relay Module
A T-GEN 50 can be operated and supervised using a 4100-3204 relay module. The relay
module is used to control the ALM- input to the T-GEN 50 and to monitor the state of its
Fault relay. The T-GEN 50 is configured to supervise the ALM- wiring from the relay
module and the 100V wiring to the loudspeakers.
Figure 6-5 shows the wiring between the T-GEN 50 and the relay module. The detail of
the 24V supply is not shown, but the T-GEN 50 0V MUST be common with the 4100ES
0V (this will always be the case when using the AUX POWER supply, as described
earlier).
