DESCRIPTON OF PACKAGE STYLES STANDARD PACKAGE The Spartan I standard package consists of either a 115V or 230V control supplied in a small metal enclosure. The speed potentiometer, fuse (s) and On/Off switch are supplied as an integral part of the cover of the box enclosure. External wiring to the motor and AC lines is accomplished by using wire nuts, which are supplied with the control.
Page 3: Open Chassis Version
In the open chassis version the heatsink with PC board, which is mounted to the box cover on enclosed Spartan I controls, is mounted on a fla t aluminum baseplate. The speed potentiometer, “On/Off “ switch , and fuse (s) are provided for customer mounting remote from the control .External connections are made to the control by wiring to the terminal...
Page 4: Control Specifications (Table Ii)
Refer to the table in Figur e 4 which gives input and armature current requirements of the various horsepower sizes in order to size external wiring properly. Pull wires of the required size into the Spartan I box and tag the wire ends to avoid mixing of the wires. - 3 -...
Page 5 If the Spartan I unit is a gasketed model (“G” prefix in front of the model number) watertight conduit fittings must be used. With the motor wiring connected to the motor but not to the control; check each of the motor leads for continuity to ground.
Page 6: Initial Turn On Procedure (Enclosed Versions)
INITIAL TURN ON PROCEDURE (ENCLOSED VERSIONS) Make sure the AC switch on the faceplate is in the “Off” position. Set the speed pot fully counterclockwise. Apply power by closing the A C disconnect switch supplying power to the control. Switch the AC switch on the control cover to the “On” position. The motor should not rotate.

3 and 4 and 1TB. CONTROL OPERATION Prior to shipment all controls are tested and completely adjusted at the Polyspede factory. Therefore, after properly wiring and furnishing AC power as explained in previous sections, the control should be capable of running the motor at the desired speed as set by the speed potentiometer.

With pot wired up the voltage between terminals 7 to 8 should vary between 0 to 6 h) Problems in control circuitry Return to Polyspede factory for repair b)Motor runs a) Motor field open or disconnected and operating under Check motor field light load.

DC contactor is energized. The bulb should not burn at any setting of the speed control pot. If the bulb does light, the Spartan I is probably defective in the case of the enclosed version. For the enclosed control go to step (f).
Page 10 This step is to be done if step (e) shows that the light bulb still lights with all external connections removed including A1, A2, F1 and F2. This probably indicates that the Spartan I's, SCRs, Field diodes, and/or power diodes are defective. The only semiconductor components that are recommended field replaceable are the power diodes located in the rectifier assembly mounted on the U shaped heatsink.

If occasional fuse blowing occurs, an intermittent short or ground is indicated. Inspect motor leads on motor brush pigtails for possible faults. Inspect Spartan I unit for loose foreign objects. (washers, nuts, wire clippings, etc) Test all external wiring. If the problem seems to be in the DC motor, refer to the Motor Tests Section.
Page 12: Control Maintenance
MAINTENANCE MOTOR Polyspede motors are rugged machines specifically designed for SCR controllers. There are no adjustments to make and maintenance is quite simple. All moving parts are subject to wear. Brushes are perhaps the only component requiring periodic maintenance.
Page 13: Maintenance - Speed Reducer
MAINTENANCE – SPEED REDUCER 1. Use type and grade of oil specified on the gear nameplate. Keep in mind proper viscosities for various temperatures. Note: Most reducers are shipped from the manufacturer without oil. 2. Keep oil at proper level. 3.
