Setting up possibilities
One or two channel display (standard)
Delta function: channel 1 - channel 2
Delta is displayed in channel 2 and all
limit functions are active on the delta
function. Addresses DIM and DP are auto-
matically transferred to channel 2.
Delta function is indicated in display as (∆)

Relay inactive
Relay in "minimum security" de-energises
when value is below set point, on power
failure or unit fault
Relay in "maximum security" de-energises
when value exceeds set point, on power
failure or unit fault
Relay de-energises on cable open
circuit, on power failure or unit fault
