Installation And Operating Instructions; Battery Connection; Startup - Grundfos Fire Control FS1 VdS Installations- Und Bedienungsanleitung

If the controller is delivered separately, e.g. in case of a Flex
version or replacement, the following additional connections have
to be made as well:
• Connect the two batteries to terminal block X1. Connect L+ of
battery A to terminal 1 and L+ of battery B to terminal 3.
Connect starting relay 1 to terminal 4 and starting relay 2 to
terminal 5. Connect the common negative potential to
terminal 2.
• Connect the generator to terminal block X3. Connect B+ to
terminal 14, D+ to terminal 17, the negative potential to
terminal 16 and the speed signal from the generator to
terminal 15. If the signal from a speed sensor is to be used for
speed indication instead of the speed signal, connect the
speed sensor to terminals 21 and 22 of terminal block X3.
• Connect the stop valve for interruption of the fuel supply to
terminal 13 (digital output) of terminal block X3.
• Connect the following sensor cables from the fire pump set to
the analog inputs of terminal block X3.
Sensor cable
Temperature sensor
Oil pressure sensor
Level sensor, fuel tank
