4.3 Displays and Settings
On the left hand side of the WRM60 X panel is the WBUS connection section already discussed in §2.2.4.), also
present:
1. Two clamps: INP is a configurable digital or analogue input via jumper JP14 and OUT is a dry contact
output (from relay). The OUT LED indicates the status of the OUT output.
2. Dip-Switch for setting the device address and two status LEDs in red and green.
3. The two-colour Red/Green LEDs PV-A and PV-B indicate the status of each charging channel.
4. The STATUS LEDs indicate the current status of the controller.
The meanings of the various LED combinations are described in the respective tables.
When switched on, the LEDs show the reset sequence. Pic.14 shows how to interpret the information it contains,
regarding the Fw version and the autodetect of the detected system voltage. Ex. a hypothetical rev 1.2 will be
indicated by one red and two green flashes; a 48V system detection will be indicated by three flashes of both red
and green LEDs. During this short sequence the PVA and PVB LEDs will be orange and always on.
