Description
The operating mode of the
RELAY optionally built into the
device can be set with this
parameter. If it is set to "by
PV," the RELAY operates
based on t 1 he triggering
(P14) and releasing (P15)
values set.
The "No ECHO" setting
enables a switched (relay
contact) error signal
to the process controller.
Caution! When the device is
de-energized, the relay
releases, so C1 is ON.
