Troubleshooting guide

2. Safety Considerations

 Read and understand all related instructions and documentation before attempting to install or

maintain this equipment

 Observe all special instructions, notes, and cautions.

 Act with care and exercise good common sense and judgment during all installation, adjustment,

and maintenance procedures.

 Ensure that all safety rules, work procedures, and standards that are applicable to your company and

facility are followed during the installation, maintenance, and operation of this equipment.

2.1 General Safety

The MPC was designed as a controller for operation solely with Pulsafeeder metering pumps. Use for

any other application is considered un-safe and voids all certification markings and warranties.

2.2 Electrical Safety

The MPC can be considered an industrial process controller. Improper application and use can be

hazardous. You are solely responsible for its use.

The MPC's electrical installation must conform to all relevant electrical codes. Installation and

electrical maintenance must be performed by a qualified electrician. Before installing or servicing this

device, all power must be disconnected from the source at the main distribution panel.

The MPC emits electro-magnetic energy and may generate radio frequency interference. Its use is

restricted to industrial applications. You are responsible for shielding this energy/interference.

Certain wiring procedures may require that the user wear a wrist strap to dissipate static charges.

Wait a minimum of 3 minutes after disconnecting power before servicing the MPC or pump

motor. Capacitors retain a charge even after power is removed from the controller.

2.3 Mechanical Safety

Users should note that the pump motor is always under the control of the MPC, and as such may actuate

without warning. Care should be taken to keep loose clothing and other objects away from the pump

motor.

The MPC was designed to be service free. It contains no user-maintainable components. Disassemble

the MPC enclosure only for initial field wiring, or as instructed to do so within this manual. Evidence

of unauthorized disassembly shall void the warranty.

2.4 Hydraulic Safety

Thoroughly review and adhere to the contents of the your pump Installation, Operation, Maintenance

and Instruction manual for installation of your Pulsafeeder metering pump. As a microprocessor

controlled device, the MPC may activate the pump motor without warning – generating hydraulic

pressure and fluid flow. Care should be taken to protect both users and systems should the pump

activate.
