Alarms for Mass battery chargers
The Mass battery chargers come standard with alarms. The following alarm signals are indicated on the Read Out Module on the front of the Mass chargers via LED combinations:
1 + 6 = Voltage sense error
2 + 6 = Battery charger temperature too high
3 + 6 = Short circuit on output
4 + 6 = Battery voltage too high/low
5 + 6 = Battery temperature sensor error
In addition to these visual alarms, all Mass battery chargers have a potential-free relay contact.
Charger Status Interface (CSI) with combined DC alarm, active as standard
Relay contact is activated (no alarm) if:
- Charger on (AC on input, switch turned to ‘on’).
- Temperature sensor within range.
- DC voltage within range.
- No short-circuit on output.
- Voltage sense (cable loss less than 3 V).
Relay contact is disabled (alarm situation) if:
- Charger off (no AC on input, switch turned to ‘off’).
- Temperature sensor out of range.
- DC voltage out of range.
- Short-circuit on output.
- Voltage sense (cable loss more than 3 V).
- General malfunction of the charger.
The DC alarm only works if the battery charger is switched on. If you require a permanent DC alarm, regardless of whether the charger has input voltage and/or the charger is turned on, select the DC Alarm setting.
Optional: A separate CSI alarm is optionally available for the Mass battery chargers and is placed in the connection box (if you require multiple alarms). Product code 21702000.
DC alarm, active after programming DIP switch
Relay contact is activated (no alarm) if:
- DC voltage is within range
Relay contact is disabled (alarm situation) if:
- DC voltage is out of range.
The DC alarm works whether or not the charger has input voltage and/or the charger is turned on or off. Programming of the DIP switch is marked with continuous monitoring mode (ContMon).
Optional: A separate DC alarm is available for all Mass battery chargers and is placed in the connection box (if you require multiple alarms). Product code 21702100.
Mass Charger Interface
Every Mass battery charger can be equipped with an intelligent front panel. The Mass Charger Interface combines the following functions:
- LCD display: DC voltage and charge/discharge current.
- Alarm functions: DC high/low voltage alarm visual/acoustic and potential-free contact.
- Alarm functions: AC alarm, no input voltage AC visual/acoustic and potential-free contact.
- CSI alarm: Charger Status Interface, charger error visual/acoustic and potential-free contact.
The Mass Charger Interface makes your Mass battery charger suitable as a power supply/battery charger for devices such as GMDSS emergency systems for seagoing vessels and yachts. The alarm settings, charge current and charging method can easily be adapted using the LCD display and control button, and the front display can be easily and quickly installed on the charger. The Mass Charger Interface is optional and is delivered complete with shunt and detailed manual. The battery charger needs to be separately ordered.
Operating principle:
For professional use: GMDSS
For the professional user, there is a front display with alarm functions according to GMDSS available. The GMDSS (“Global Maritime Distress and Safety System”) is a global maritime communication system which is part of SOLAS (Safety Of Life At Sea), using DSC and satellite communications.
