2. 000 ohms then the seal fail indicator for that pump will be turned on This action does not disable the pump however it does demote the pump to the lag position in the alternation order The pump controller has two inputs for pump temperature sensors If the controllers detects a short between these inputs and ground then a temperature failure condition does not exist If the short to ground is removed then a temperature failure condition exists and the pump associated with that in put will be disabled and the Temp Fail indicator illuminated This condition does not latch up and will return to normal if the short to ground is reestablished All of the float and sensor inputs are transient protected and filtered to prevent electrical interference from causing improper operation PRIMEX 2 PC 1000 Specifications The controller has two switches that select what mode the two pumps are in These HOA switches have the following function H When in HAND the pump will be constantly called to run O When in OFF the pump will be off A When in AUTOMATIC the pumps will be called by the pump controller The Hand and Off functions of these switches will operate even if the controller is off or has failed The controller has a switch that is used to select the lead pump When this switch is in the center position ON then the two pumps will alternate as lead pump each pump cycle When in the 1 2 po sition then pump one is the lead and when in the 2 1

5. ll then turn on the lead pump If this pump causes the water level to fall the lead pump will be turned off when both the Lead and Off float are out of the water and open If the lead pump is not sufficient to control the water level then the lag pump will be started when the Lag float closes The two pumps will not be turned off until the Lag Lead and Off floats are out of the water and open at which time all pumps will be turned off The controller has delays built into the software which will insure that whenever a pump is turned on the second pump cannot come on for at least 8 seconds Another delay insures that when a pump is turned off the other one cannot turn off for 4 seconds These delays help insure smooth pump opera tion and prevent excessive electrical surges The last float input is for the High float Whenever the high float is under water closed then the high alarm condition is set When a high alarm condition is set the alarm light will flash on and off and the horn will be activated The horn can be silenced using an external mute button connected to pin j2 9 Both the alarm light and horn will turn off when the high float input opens The PC 1000 has an alarm test button on the front panel which can be used to test the alarm horn and light The pump controller has two inputs for pump seal fail leak sensors one for each pump These inputs measure the resistance between the input and ground If the resistance is less than 50
6. position pump two is the lead The controller has two inputs which should be connected to the auxiliary switches on the two motor starters These inputs when shorted cause the pump running indicators to be illuminated Using these inputs may eliminate the need for panel mounted pump running lamps 3 0 SPECIFICATIONS 3 1 Float and Sensor Input There are four float inputs two leak sensor inputs and two temperature fail inputs They use current limiting resistors and a zener diode for transient protection They also have a resistor capacitor filter as well as a software filter to avoid electrical interference They have the following specifications Short circuit current less than 2 mA Open circuit voltage 5 0 VDC 3 2 Aux contact inputs There are two sets of inputs for the auxiliary contacts on the motor starters When these inputs are shorted the pump running lamps are illuminated These inputs have the following specifications Short circuit current less than 2 mA Open circuit voltage 12 0 VDC 3 3 Relay outputs There are three form A SPST relay outputs Two are to call the pumps and one for the seal fail They have the following specifications Maximum current at 120 VAC 5Amps with a resistive load Maximum voltage 140 Volts 3 4 Driver outputs There are two 12VDC driver outputs They are used to drive the alarm light and alarm horn which must be 12VDC devices or 12VDC relays They can drive a maximum of 100 MA
