Answers

Can it use high and low level float switches as fail-safes while using a level sensor for pump control?  [top]
Any unused or additional digital I/O can monitor the high and low level float switches. When either of these conditions exist, they can activate/deactivate a relay that interrupts the power going to the pump controls.

Can it control more than 2 pumps?  [top]
You can control more than 2 pumps based on additional level setpoints or switches but only 2 of the pumps will be in the alternation scheme.

For example,
cycle 1 - Pump 1 lead, Pump 2 lag, Pump 3 next and Pump 4 last
cycle 2 - Pump 2 lead, Pump 1 lag, Pump 3 next and Pump 4 last

Can over temperature conditions be used to stop the pumps?  [top]
Yes, by having the over temperature digital input control a relay that is in series with the pump control relay, it can be interrupted when there is an over temperature condition, preventing the pump from running.

The Elite drives the Overtemp relay when the overtemp signal for that particular pump is sensed.

Can it monitor level at one location and control pumps at another location?  [top]
Yes, this is very typical for water towers/tanks and remote wells. The float-switch Pump Control Option is installed at remote well since it is performing the actual pump control. An Elite at the tank simply monitors the level and calls the remote unit when the level indicates that a pump should run.

The level is monitored at the tank with either a level sensor or a series of float switches. When the appropriate level setpoint or float switch condition is met, the Elite at the tank calls to the remote Elite at the well and turns on a relay. The relay at the remote site is wired back into a digital input indicating a float switch is active and then the Pump Control turns on the appropriate pump.

Can it access the pump status information over the phone, fax or web?  [top]
Yes, the pump run times, pump starts and current pump status is available over the phone, fax and web. The information over the phone is spoken when requested and via fax and the web is presented in report format.

Can it be used as a cell-phone based system?  [top]
Yes, any Elite configuration is available with an integral analog, CDMA or GSM phone.

Can the HOA (Hand, Off, Auto) switch be monitored?  [top]
Yes, the HOA switch is connected to the OVERRIDE digital input channel for each pump. When the switch is in the H or O position, the Pump Control of the Elite will not turn the pumps on, but will still compute pump run times if the pumps are run manually.

Can it control the amount of water that is pumped to another jurisdiction, shut off for the day and then start over the next day?  [top]
Yes, by using the existing Totalizer function on a digital input and setting a limit, you can control the pumps to pump a predetermined amount of water on a daily basis.

For example,
A municipality has a contract to pump 50,000 gallons of water a day to another municipality. The pumping station has a flow meter that provides a pulse for every 100 gallons pumped. The Elite can be programmed as follows:
Connect a flow meters pulse output to any spare digital input channel - say channel 41.

  • Channel Mode - Call on Limit
  • Totalizer Limit - 50,000
  • Scaling value - 100 (each pulse is 100 gallons)
  • Engineering Units - 6 (gallons)
  • Limit Reset Period - 1440 minutes (1 day)
  • Relay channel to activate - 23 (relay that is connected in series with the pumps)
  • Relay state on Normal to Alarm - de-energized

The Elite counts pulses whenever there is flow. When the Totalizer Limit is reached, Relay 23 will be opened, which prevents the pumps from running any more on that day. At midnight, the totalizer automatically starts over.

Can a user add I/O to a unit?  [top]
Yes, there are 3 full slots that are available for adding any combination of I/O cards.

What are the key benefits to using the Pump Control Option over a PLC implementation?  [top]
