If current through the temperature sensor exceeds the values listed, an intermediate control circuit relay must be used to reduce the current or the sensor will not work properly. TEMPERATURE SENSOR ELECTRICAL RATINGS Volts Continuous Amperes Inrush Amperes 110-120 3.00 30.0 220-240 1,50 15.0 440-480 0.75 7.5 6 1 0.60 1 6.0 C-4.2-2) Single Phase (Standard) - The type of in -winding overload protector used is referred to as an inherent overheating protector and operates on the combined effect of temperature and current. This means that the overload protector will trip out and shut the pump off if the windings become too hot, or the load current passing through them becomes too high. It will then automatically reset and start the pump up after the motor cools to a safe temperature. In the event of an overload, the source of this condition should be determined and rectified immediately. DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION OCCURS! C-4.3) Moisture Sensors- DS Models: (Optional) A normally open (N/O) detector is installed in the pump seal chamber which will detect any moisture present. It is recommended that this detector be connected in series to an alarm device or the motor started coil to alertthe operator that a moisture detect has occurred. In the event of a moisture detect, check the individual moisture sensor probe leads for continuity, (- resistance = no moisture) and the junction box/control box for moisture content. The above situations may induce a false signal in the moisture detecting circuit. If none of the above tests prove conclusive, the pump(s) should be pulled and the source of the failure identified and repaired. IF A MOISTURE DETECT HAS OCCURRED SCHEDULE MAINTENANCE AS SOON AS POSSIBLE. C-4.4) Wire Size: Consult a qualified electrician for proper wire size if additional power cord length is required. See table on pages 9 and 10 for electrical information. SECTION: D START-UP OPERATION D-1) Check Voltage and Phase: Before operating pump, compare the voltage and phase information stamped on the pump identification plate to the available power. D-2) Check Pump Rotation: Before putting pump into service for the first time, the motor rotation must be checked. Improper motor rotation can result in poor pump performance and can damage the motor and/or pump. To check the rotation, suspend the pump freely, momentarily apply power and observe the kickback". "Kickback" should always be in a counter -clockwise direction as viewed from the top of the pump motor housing. D-2.1) Incorrect Rotation for Three -Phase Pumps: in the event that the rotation is incorrect for a three-phase installation, interchange any two power cord leads at the control box. DO NOT change leads in the cord housing in the motor. Recheck the "kickback" rotation again by momentarily applying power. 9 D-2.2) Incorrect Rotation for Single -Phase Pumps: In the unlikely event that the rotation is incorrect for a single phase pump, contact a Barnes Pumps Service Center. D-3) Identification Plate: Record future serial plate information in the "NOTES' section. D-3.1) Pump -Down Test: After the pump has been properly wired and lowered into the basin, sump or lift station, it is advisable to check the system by filling with liquid and allowing the pump to operate through its pumping cycle. The time needed to empty the system, or pump -down time along with the volume of water, should be recorded on the start-up report. SECTION E: PREVENTATIVE MAINTENANCE As the motor is oil filled, no lubrication or other maintenance is required, and generally Barnes Pumps will give very reliable service and can be expected to operate for years on normal sewage pumping without failing. In our experience attempts at preventative maintenance are more likely to reduce: rather than extend the life of our pumps. However, if you are inclined to perform preventative maintenance, the following are the steps that should be performed. 1) Inspect motor chamber for oil level and contamination and repair as required per section F-1. 2) Inspect impeller and body for excessive build-up or clogging and repair as required per section F-2, 3) Inspect motor and bearings and replace as required per section F-3. 4) Inspect seal for wear or leakage and repair as required per section F-4.
