Relay Status - Danfoss Cascade Operating Instructions Manual

Relay status

The display panel on the VLT allows reading
the status of the relays.
Press the [DISPLAY MODE] key. Use the [+] and [-]
keys to scroll through the list to RELAY STATUS. The
relay status readout consists of 8 binary digits. The
first digit (starting from left) indicates the status of
Relay 01 which is located in the power section of the
VLT. The second digit is Relay 02 which is located
on the VLT control card. Digits 3 - 6 indicate the
four relays of the cascade controller, relays 06, 07,
08 and 09 which are located on the option board.
Digits 7-8 are reserved for future use.
The readout can be very useful during commissioning
to see how many fixed speed or slave
pumps are in operation.
