Controls and Indicators (continued)
Switches
Two switches are provided on the right side of the ALM to effectively
disconnect the relay coils from the inverter’s supply voltage (11 VDC), thus
preventing the relays from engaging if a control signal is sent out from the inverter.
This safety feature allows you to work with the auxiliary relays without having to
power-down the connected inverter.
AUX RELAY Switch
The AUX RELAY switch enables the relays by providing the operating voltage to
the relay coils RY9 and RY10. When the relays are enabled, they will respond to the
control signals provided by the inverter. When the switch is in the RELAYS
DISABLED position, the inverter control signals have no effect on relay operation
(i.e., the COM and N.C. contacts engage). This switch does not affect the operation
of the LEDs which continue to light whenever the inverter sends a CLOSE CONTACT
command to the relays.
INVERTER ERROR Switch
The INVERTER ERROR switch provides a simple way to test an externally
connected alarm. Once the alarm is tested, this switch should be set to the RELAY
READY position.
