selected.
RELAYS
When the RELAYS option is selected from the SETUP menu, the operator is prompted to select
which relay is to be configured. There are five menu options for configuring the setpoint relays.
OP MODE - defines operation mode of relay as a high or low setpoint.
ON SETPOINT - defines when the relay will energize.
OFF SETPOINT - defines when the relay will de-energize.
FAIL MODE - defines the relay state during an alarm condition (no change, ON, or OFF).
CH ASSIGN - defines to which sensor the relay is assigned. A sensor may be assigned to more
than one relay.
There are four menu options for configuring the clean relays.
SYSTEM TYPE - defines what type of cleaning system is used.
CLEAN SCHEDULE - defines how often a cleaning cycle will occur.
CLEAN JET TIME - defines duration of time the clean relays will be energized.
CLEAN RECOVERY TIME - defines how long the reading holds after the clean cycle has ended.
Note: Do not attempt to adjust relay set points values until
a working sensor has been connected to the channel.
Otherwise, the analyzer may not display the correct units
(TSS or D.O.) for the channel.
Low Setpoint
If a relay “OP MODE” has been set as a LOW setpoint, then the corresponding relay will energize if
the reading falls below the value set in the “ON SETPOINT” parameter. Once the relay has been
energized by a low reading, it will not be de-energized until the reading rises above the value set in the
“OFF SETPOINT” parameter. The relay “OFF SETPOINT” value MUST be greater than or equal to the
“ON SETPOINT” value in this mode.
High Setpoint
If a relay “OP MODE” has been set as a HIGH setpoint, then the corresponding relay will energize if
the reading rises above the value set in the “ON SETPOINT” parameter. Once the relay has been
energized by a high reading, it will not be de-energized until the reading falls below the value set in the
“OFF SETPOINT” parameter. The relay “OFF SETPOINT” value MUST be less than or equal to the “ON
SETPOINT” value in this mode.
