Pumptec-Plus

Pumptec-Plus is a pump/motor protection device designed to work on any 230 V single-phase induction motor (PSC, CSCR, CSIR, and split phase) ranging in size from 1/2 to 5 horsepower. Pumptec-Plus uses a micro-computer to continuously monitor motor power and line voltage to provide protection against dry well, water logged tank, high and low voltage and mud or sand clogging.

Pumptec-Plus – Troubleshooting During Installation

SYMPTOM

POSSIBLE CAUSE

SOLUTION

Unit Appears Dead		Check wiring. Power supply voltage should be applied to L1 and L2 terminals of the
	No Power to Unit	Pumptec-Plus. In some installations the pressure switch or other control devices is wired
(No Lights)
		to the input of the Pumptec-Plus. Make sure this switch is closed.
		Pumptec-Plus is calibrated at the factory so that it will overload on most pump systems
	Unit Needs to Be Calibrated	when the unit is fi rst installed. This overload condition is a reminder that the Pumptec-
Flashing Yellow Light		Plus unit requires calibration before use. See step 7 of the installation instructions.
	Miscalibrated	Pumptec-Plus should be calibrated on a full recovery well with the maximum water fl ow.
		Flow restrictors are not recommended.
		Step C of the calibration instructions indicate that a fl ashing green light condition will

		button. The green should start fl ashing.
		During the installation of Pumptec-Plus power may be switched on and off several times.
	Power Interruption	If power is cycled more than four times within a minute Pumptec-Plus will trip on rapid
Flashing Red and		cycle. Press and release the reset button to restart the unit.
Yellow Lights		A bobbing fl oat switch may cause the unit to detect a rapid cycle condition on any motor
	Float Switch	or an overload condition on two wire motors. Try to reduce water splashing or use a
		different switch.
	High Line Voltage	The line voltage is over 253 volts. Check line voltage. Report high line voltage to the
		power company.
Flashing Red Light
		If you are using a generator the line voltage may become too high when the generator
	Unloaded Generator	unloads. Pumptec-Plus will not allow the motor to turn on again until the line voltage
		returns to normal. Over voltage trips will also occur if line frequency drops too far
		below 60 Hz.
	Low Line Voltage	The line voltage is below 207 volts. Check line voltage.
	Loose Connections	Check for loose connections which may cause voltage drops.
Solid Red Light
		If you are using a generator the line voltage may become too low when the generator
	Loaded Generator	loads. Pumptec-Plus will trip on undervoltage if the generator voltage drops below 207
		volts for more than 2.5 seconds. Undervoltage trips will also occur if the line frequency
		rises too far above 60 Hz.
