Totaliser
P210, P220 = 3 (Totaliser)
When a relay is set up as a totaliser relay, the second and third parameters
that will be displayed in the menu determine the frequency and duration of
the relay pulse.
P213, P223 - Relay Setpoint 1
The factor by which the on board totaliser (P820) should be multiplied by to
provide a relay closure, giving the frequency of the pulse.
Default = 0.00
P214, P224 - Relay Setpoint 2
The time in seconds to set the duration of the relay pulse. Default = 0.00
secs.
Common Parameters
P217, P227 - Relay Closures
This parameter displays the number of times the relay has activated since the
relay has been in use. It can be reset with any value.
P218, P228 - Relay Fail Safe
The unit has a general fail-safe parameter P808 . However, this can be
overridden so that each individual relay has its own independent fail safe
mode.
This parameter determines what the relay will do in the event of the Failsafe
Time ( P809 ) expiring.
Option Description
0 = Default Relay assumes system default mode P808
1 = Hold Relay remains in its current state
2 = De-Energise Relay will De-Energise
3 = Energise Relay will Energise
