There follows an overview of the options that are directly connected with the relay board.
These relay-connected options are activated through the relay board outputs:
-
Aquamatic
- Charging
- Charge 80%
- Charge end
- Main charge finished
- Charge OK
- Common error
- Signal lamp
- Immobiliser device
- ON
- Refill indicator
- Battery cooled
- External air pump (electrolyte circulation)
Aquamatic The Aquamatic contains the controller for a solenoid valve that automatically tops up the
water in the battery to be charged.
-
Standard setting:
-
At the start of the recharging phase, the solenoid valve opens for 12 seconds and
then closes for 6 seconds
- This cycle is repeated 26 times
- USER setting:
-
Configurable "ON" time (solenoid valve opens) after the end of the main charge
phase
Charging The "Charging" option is suitable for actuating a signal lamp for instance. While charging
is in progress, the corresponding relay picks up automatically.
Charge 80% Like the "Main charge finished" function, the relevant relay switches as soon as the battery
is 80% charged.
Charge finish The "Charge finish" option is suitable for actuating a signal lamp for instance. Once the
configured charging characteristic is fully completed, the corresponding relay picks up au-
tomatically.
Main charge fin-
ished The "Main charge finished" option is suitable for actuating a signal lamp for instance. When
the main charge phase finishes, the corresponding relay picks up automatically.
Common error
message The "Common error message" option is suitable for actuating a signal lamp for instance.
Each time an error is detected, the relevant relay picks up automatically.
Signal lamp As an alternative to the charging lights, one or more suitable lamps can be connected to
the relay board to indicate the state of charge or operating status of the charger. These
lamps can be designed for a voltage of up to 30 V DC or up to 250 V AC on a starpoint-
earthed network.
