FUNCTION
The LED will be ON when a specific relay has been enabled by the respective command received
from the Transmitter Unit. The LED will extinguish, when the command is no longer detected.
DS30
Red
Monitors the input to the Security Relay (K26).
Normally ON when the receiver is enabled.
If the system is ON and the light is not lit there is a serious microprocessor error, try replacing the
EPROM.
DS31
Red
Monitors closure of the Master Control Relay (MCR) relay.
LED will be ON when the MCR relay has been enabled by an ON command received from the
Transmitter Unit. LED will extinguish, when an OFF command has been transmitted, an ESTOP
condition is present, or SW2 is set to OFF.
The MCR controls the power to the Main Line Contactor. If it does not come ON in normal
operation check that SW2 is ON and no ESTOP condition exists.
DS32
Red
Monitors closure of the Security Relay output (K26).
The LED will be ON when the Security Relay has been enabled by an ON command received
from the Transmitter Unit. LED will extinguish when an OFF command is transmitted, or an
ESTOP condition is present.
The Security Relay controls the 12 VDC power to the MCR relay (MR). If DS30 is ON and not
DS32 check that switch SW2 is ON if SW2 is ON then try replacing the security relay K26.
