Counters
To view the Counters menu:
1. From the Home screen, select 3: Service Tools .
2. Select 4: Maintenance .
3. Select 2: Counters / Timers .
4. Select 1: Counters .
The Counters / Timers menu displays the following counters:
• Sensor Wet Count – This counter increments each time the PV
(Output State) changes from Dry to Wet. This
counter can be reset or preset by setting a new
value
.
• Calibration Count – The 2160 is calibrated under reference
conditions at the factory. In special
circumstances, it may be re-calibrated in the
field and this increments the counter.
• Fault Count – This counter increments each time there is a
Fault condition (see “Sensor Status” on
page 2-18). This counter can be reset to zero.
Sensor Status Sensor State

(1) Sensor Fault Delay (page 2-13) delays the update of Sensor State when the operation mode is
Enhanced.
PV (Output Status)
Valid Dry 0.0 (Dry)
(2)
(2) PV is not changed.
Fault Too Dry (Fault) 1.0 (Wet)
