SCADA FEATURES
Disabling Pump Operation
To Disable a Pump set Coil 149, 150, 151, or 152 in Register 40010. To return a pump to normal operation, clear the
respective Coil.
Upon a loss of serial communication, the Pump Disable Logic will be automatically reset, and any pump that had been
remotely disabled will be re-enabled after the delay set on Parameter P.38. For this feature to work properly, the master
must poll the Controller at intervals shorter than the time set on Parameter P.38. However, if Parameter P.38 is set on
255 the pumps will remain disabled until power is lost.
Pump On / Off and Alarm Levels
The Pump On, Pump Off, High Alarm, and Low Alarm levels may be viewed and changed at Registers 40012 - 40021.
The Level may be monitored by reading SCADA Register 40011. The value will be just what is displayed on the front
of the controller but with no decimal point. If an operator has the Controller in the Level Simulation Mode, Register
40011 will show the simulated level.
Level
Discrete Inputs
The status of all the Discrete Inputs may always be read from Coils 545 - 552 in Register 40035, Coils 561 - 568 in
Register 40036, and Coils 577 - 578 in Register 40037, regardless of what function may be assigned to the inputs.
Discrete Inputs assigned Functions 19 - 30 (Telemetry A - M) place their status in predetermined Coils, but do not per-
form any other function. The status of these inputs may be read from Coils in Registers 40001, and 40008.
Discrete Inputs assigned with Functions 7 - 8, 17 - 18 and 31 - 38 perform their respective function and place their status
in predetermined Coils. The status of these inputs may be read from Coils in Registers 40001, and 40008.
The optional Auxiliary Analog Inputs may be used to monitor such things as flow, pump speed, motor current, or what-
ever is connected to them. The inputs perform no control function inside the Controller. The Data may be read in either
an 8-bit or 10-bit format .
The 8-bit version of the data may be viewed on the front of the controller under Parameters n.19 - n.22.
The Data in an 8-bit format (0 - 255), may be read from Registers 40042 - 40045.
The Data in a 10-bit format (0 - 1023), may be read from Registers 40071 - 40074.
Auxiliary Analog Input Data
Level Monitoring
In cases where the pumps empty or fill a remote tank, the SCADA system Master may be programmed to collect the
level data from the remote tank and write the level to SCADA Register 40025 in the Controller. For the Controller to
follow the value in Register 40025, Parameter F.19 must be set on 4. Also, the value written to Register 40025 must
already be scaled into feet as it would be displayed on the front of the Controller, but with no decimal point. The
decimal point is artificially inserted by the Controller based on Parameter P.36. For example, a level of 8.6 feet
would be written as 86 (assuming that Parameter P.36 = 1).
If SCADA communication is lost, Register 40025 will no longer receive current level data. With the loss of communi-
cation the Controller will turn off all pumps and turn on the Fault indicator and place Fault Code 37 in Parameter FLC.
The Level Display will also flash and show the last value written to Register 40025. Loss of communication is estab-
lished when the delay set on Parameter P.38 expires. The time delay setting on Parameter P.38 must be set long
enough so that it will not time out during the interval between normal communication events.
