The ESD5330 series speed control unit is rugged enough to be placed in a control cabinet or engine mounted enclosure with other dedicated control equipment.The circuit board is conformally coated to seal out moisture and resist vibration.If water,mist or condensation can come in contact with the controller,it should be mounted vertically.This will allow any accumulated fluids to drain away from the speed control unit.

2)WIRING

The electrical connections are illustrated in figure 1. on page 3. Actuator and Battery connections to terminals ABC and D should be appropriately sized with respect to to maximum current consumption of the actuator that is being used. Long cable runs require an increased wire size to minimize voltage drops.

Battery positive (+) input, Terminal D, should be fused for 20 Amps as illustrated to protect system wiring.

The magnetic speed sensor connections to Terminals E and F must be shielded for their entire length. The speed sensor cable shield should only be connected to the case as shown.

The shield should be insulated to insure that no other part of it comes in contact with engine ground, otherwise, stray signals may be introduced into the PER5330 causing erratic operation.
