SCADA FEATURES
Pump 1-4 Speed References may be read from Registers 40038 - 40041. The values are in percent of full speed (0 -
100%). The speed reference for a pump that is turned off is made zero, even when Parameters F.23 - 26 are set on 5.
Pump Speed Reference
Pump 1-4 Elapsed Time Meters may be read from Registers 40003 - 40006. The values read from these registers are
intended for use in comparing the pump run time of one pump with the run time of the other pumps at the station, for the
purpose of checking for uneven run times. (Uneven run times is an indication of a maintenance problem with one of the
pumps.) Periodically the comparison of run times should be made and the registers should reset to zero. The ETM data
is stored in non-volatile memory just prior to a total loss of internal 5V power, so the data is not lost during a power out-
age. (However, if the serial port is being polled as a power outage occurs, the most recent data may occasionally be
lost.) To reset one of the ETMs to zero, momentarily set the respective Coil (21 - 24) in Register 40002.
Elapsed Time Meters
Low Level Telemetry
The Low Level Alarm is generated from a comparison of the displayed Level with the Low Level alarm setting. This
alarm works when Parameter F.19 is set on either 1, 2 or 3. The status of this alarm may be read from Coil 130 in Reg-
ister 40009. This alarm will also set Coil 2 in Register 40001.
The Low Float Alarm is generated by the closure a float switch connected to a Discrete Input programmed for either
Function 17 or 32. The status of this alarm may be read from Coil 128 in Register 40008. This alarm will also set Coil 2
in Register 40001.
The Probe Backup Low Level Alarm is generated when liquid uncovers the Low Level Electrode of a Level Probe In-
put. Parameter b.01 must be setup with the number of the Level Probe Input used to read the Low Level. The status of
this alarm may be read from Coil 121 in Register 40008. This alarm will also set Coil 2 in Register 40001.
Fault Codes
The Fault Code (Parameter FLC) may be read from Register 40047.
The Last Fault Code (Parameter LFC) may be read from Register 40048.
The Fault Code and the Last Fault Code may be reset by setting Coil 31 in Register 40002.
High Level Telemetry
The High Level Alarm is generated from a comparison of the displayed Level with the High Level alarm setting. This
alarm works when Parameter F.19 is set on either 1, 2 or 3. The status of this alarm may be read from Coil 129 in Reg-
ister 40009. This alarm will also set Coil 1 in Register 40001.
The High Float Alarm is generated by the closure a float switch connected to a Discrete Input programmed for either
Function 18 or 38. The status of this alarm may be read from Coil 120 in Register 40008. This alarm will also set Coil 1
in Register 40001.
The Probe Backup High Level Alarm is generated when liquid covers the High Level Electrode of a Level Probe Input.
Parameter b.07 must be setup with the number of the Level Probe Input used to read the High Level. The status of this
alarm may be read from Coil 122 in Register 40008. This alarm will also set Coil 1 in Register 40001.
