Low Electrolyte. 

Ensure the Low Electrolyte Alarm is not inhibited. 

Remove the electrolyte probe (if fitted) and check for 

Low Electrolyte

 fault indication on the 

LCD  panel.  Check  that  the  low  electrolyte  relay  on  the  Relay  board  A4  (if  fitted)  have  de-

energised and that its contacts (see Schematic Diagram) have changed over. Also check that 

Common  Alarm  relay  on  the  Interface  Card  has  de-energised  and  that  buzzer  is  sounding. 

Ensure that the buzzer can be muted by pressing the 

Alarm Mute

 switch. The mute function 

can be reset by pressing the 

Reset

 switch.  

Replace the electrolyte probe

 

 

7.11 

Battery Fail 

 

Disconnect the battery from the charger. Press the 

Battery Test

 switch and check that after the 

test period the 

Battery Fail

 LED lights up. Check that the battery fail relay on the Relay board 

A4 (if fitted) have de-energised and that its contacts (see Schematic Diagram) have changed 

over. Also check that the Common Alarm relay has de-energised and that buzzer is sounding. 

Ensure that pressing the Alarm Mute switch can mute the buzzer.  
 

Reconnect the battery.  

 

Note:

 In order to clear this alarm, the battery must be reconnected and the Battery Test switch 

must be pressed to initiate another battery test cycle. The alarm will then clear if the battery 

passes the test. 

 

7.12 

Diode Voltage droppers  (Optional) 

This feature is optional.
