Cleaner Relay Output (Advanced)
Automatic sensor cleaning can be accomplished
using any one of the three relay outputs. At
a prescribed time interval, a Cleaner Relay
Output will energize and allow the activation
of a cleaning device. While in the energized
state, analog and relay outputs can be held to
values captured just prior to the cleaning
cycle (i.e., energized state). If a relay
hold condition is not feasible, non-cleaner
relay outputs can be disable during a cleaning
cycle.
To specify a cleaning cycle, the Cycle, On,
and Recovery Times must be defined. The Cycle
Time defines the repeating period between
cleaning cycles, the On Time defines the
length of time the relay will be energized,
and the Recovery Time defines the length of
time after the relay has been de-energized
before the hold and/or disable condition(s)
will be removed. Valid times for Cycle Time
are 0.0 to 99.9 hours and for On and Recovery
Times are 0.0 to 99.9 minutes.
