Solid State Relay Outputs (
RELAY
)
The meter is optionally equipped with two solid state relays that may be set up for alarms, timer, or pump
control. Alternatively, they may be disabled.
Alarms are available based on the PV value or the digital input. The alarm status will show on the display
even if the output is not wired.
Pump control allows the relay to turn on and off a pump at specified on and off points. This can be done
using only one of the relays to control one pump (
ON‐OFF
) or using both relays in tandem to alternate
between two different pumps (
ALTERN
).
A timer output (
TIMER
) turns the relay on and off at the specified time intervals. The timer can be set as
single-shot or continuous timer.
The stopwatch output (
STPWATCH
) allows the relay to be manually activated by starting the stopwatch.
The stopwatch count can be displayed on the top or bottom line.
The output may be disabled by selecting
DISABLE
.
Caution!
During setup, the relays do not follow the
input and they will remain in the state
found prior to entering the Relay menu.
