ACTIVATION
(configuration values)
The group of configuration settings available to a relay is
dependent on its selected function mode (ALARM,
CONTROL or TIMER).
Relays set for STATUS function
are not configurable.
Table A describes all relay configu-
ration settings, categorized by relay function mode:
Table A -- RELAY CONFIGURATION SETTINGS
Setting Description
For ALARM Relay
Low Alarm Sets the value at which the relay will turn on in
response to decreasing measured value.
High Alarm Sets the value at which the relay will turn on in
response to increasing measured value.
Low
Deadband Sets the range in which the relay remains on after the
measured value increases above the low alarm value.
High
Deadband Sets the range in which the relay remains on after the
measured value decreases below the high alarm value.
Off Delay Sets a time (0-300 seconds) to delay the relay from
normally turning off.
On Delay Sets a time (0-300 seconds) to delay the relay from
normally turning on.
For CONTROL Relay
Phase A “high” phase assigns the relay setpoint to respond
to increasing measured value; conversely, a “low”
phase assigns the relay setpoint to respond to de-
creasing measured value.
Setpoint Sets the value at which the relay will turn on.
Deadband Sets the range in which the relay remains on after the
measured value decreases below the setpoint value
(high phase relay) or increases above the setpoint
value (low phase relay).
Overfeed
Timer Sets the time (0-999.9 min.) to limit how long the re-
lay can remain “on.” For more details on overfeed
timer operation, see Part Three, Section 7.
Off Delay Sets a time (0-300 seconds) to delay the relay from
normally turning off.
On Delay Sets a time (0-300 seconds) to delay the relay from
normally turning on.
For TIMER Relay
Interval Sets a time (0-999.9 min.) to establish how long the
relay remains “off” before it starts a sensor cleaning.
Duration Sets the time (0-999 seconds) to limit how long the
timer relay remains “on” (sensor cleaning duration).
Off Delay Sets a time (0-999 seconds) to establish how long
after the timer relay turns off that the analog outputs
and alarm and control relays remain “held.”
For STATUS Relay
No settings available -- status relay cannot be configured.
