RELAY BUTTON
By pressing the on the screen, you will remotely energize the relay in the RTU. The relay
will only stay ON for 2 seconds, then it will turn OFF automatically. The label text below the relay button
can be edited to describe the function of the relay. Example: “Silence Horn”.
CAUTION/DANGER
Machine may start unexpectedly and cause serious injury or death. You must have
confirmation that all personnel are free and clear from moving parts and the electrical
panel before activating the relay remotely.
Only allow qualified operators to remotely activate the relay. The relay remote operation
must be part of a fail safe electrical circuit that would shutdown the equipment before
failing or cause damage/injury.
Local and National safety codes must be followed.
ACK. FAULT BUTTON AND INDICATION
The button must be pressed after an alarm within the set time (See Setup screen). If an alarm
becomes active, the timer starts and the operator must acknowledge the alarm on the screen before
the timer times out (default value is 20 min). If not acknowledged the OK indicator turns
red
and can
be used to notify other uses of the failure to acknowledge. This function is useful if only one user is on
standby, and may not be able to respond in a timely manner. Click on to set the Alert notification.
Leave it blank if you do not wish to use this function.
STATION DATA (trending available - see Report & Trending section)
Wet Well Level:
Level of the wet well as measured by the transducer.
P1-2 Amps:
Pump Current snapshot captured 30 secs after motor start by the current transducer.
Not available when using the PC-3000X controller.
P1-2 Cycles:
The number of start cycles occurred since midnight. Note: When using the Pump
Watch
™
Express Gateway with the PC-3000X controller, this value is the previous 24h
accumulated cycle counts.
P1-2 Runtime Minutes:
Accumulated motor run since midnight. View reports (accumulation for full
run analysis day/week/month. Note: When using the Pump Watch
™
Express Gateway with the
PC-3000X controller, this value is the previous 24h accumulated Runtime.
Station In-Flow (GPM):
The measurements are calculated using the wet well level, the tank
diameter and the fill time. It is very useful data point in tracking peak flow hours and to detect
storm water infiltration issues.
P1-2 GPM:
The measurements are calculated using the wet well level, the tank diameter, the fill
time and discharge time. It is a very useful data point in tracing the performance on each pump,
and to understand the effect of changing head conditions.
Pump Data:
These values are not measured. They are used as reference and for record keeping.
It is valuable to compare the pump FLA to the actual Amps on the screen for setting High Amp
and Dry Run Alarms. It is also a quick way to check the pump data before making a service call
to the station.
