Power Supply Signals
Description
Details
MAINS FAULT
Continuity between NC & C in normal operating condition. When there is a fault condition on the
mains power, continuity is switched to NO & C. Relay is normally energized and “fail
-
safe” as the
relay will change over in the event of total power failure.
FAULT RELAY
Continuity between NC & C in normal operating condition. When there is any fault on the PSU or
Charger, continuity is switched to NO & C. Relay is normally energized and “fail
-
safe” as the relay
will change over in the event of total power failure.
PSU DATA
Serial data connection from PSU to termination PCB. TO BE USED TO CONNECT TO PANEL ONLY.
1.
Switch SW2 on the charger PCB is used to determine if temperature compensation is used or not.
Power down panel completely before removing cover to change the setting.
2.
Battery circuit resistance measurement is required by BS EN 54-4. The maximum resistance of several
tens to hundreds of milliohms varies for different power supplies and depends on their nominal
output voltage and power. It can be set on or off by using switch 4 of dip switch SW1 on the charger
PCB. Power down panel completely before removing cover to change the setting.
