Mounting Wiring is done to unpluggable terminal strips on the rear of the unit. There are three ways to mount: • On door or raceway - use cutout template • Panel mount - use template + optional Bezel Kit (no charge) • On wall - on standard outdoor junction box + optional Outlet Box Adapter (no charge) Voltage 120 volts AC is taken from two of the phases. If the motor starter already has a 120-volt control transformer with 10VA of free capacity, it can be used.

Otherwise, install a separate transformer. It is okay if the secondary is grounded. BE SURE TO NOTE WHICH TWO PHASES SUPPLY THE TRANSFORMER. In a 120/208V three-phase system, the 120V MUST come from a transformer connected to two of the phases. The 120V phase to ground voltage cannot be used. Current The current signal is taken from the REMAINING phase. This current sample passes through the Range Finder Toroid.

So every time you get a new RC car, three-hole punch the instruction manual and put it in a three-ring binder.

It is VERY IMPORTANT that the current signal comes from the phase that IS NOT supplying the 120V control transformer. Be extra careful when the machine has reversing starters or multi-speed windings.

If a wrong phase is used, the control will either: • Work backwards • Have reduced sensitivity. 4-20 MILLIAMP ANALOG OUTPUT The Analog Output is directly proportional to Full Scale capacity. It is always active.

500 ohm maximum connected impedance. Terminal 2 - 4-20mA - Positive Terminal 3 - 4-20mA - Negative Use twisted pair or in noisy environments, use shielded cable. Ground shield at other end. Use the Full Scale capacity from the chart to scale external meter, chart recorders or computers.

THE PMP-25 POWERS THE 4-20MA SIGNAL DON'T USE AN EXTERNAL DC POWER SUPPLY. TO SET FULL SCALE • After hook-up, find your HP, KW or% from the chart. • Decide if you want to display HP,% or KW.

• The Scalecycles through the choices shown below and blinks slowly for each choice. Each press of Scalemoves you to the next choice FRONT PANEL SET-UP TIPS 1.None of the settings will be changed until you hold down and the fast blinking stops. 2.Five seconds after you have pressed a button, the control will return to normal operation. Olympus Cyf-v2 Manual. 3.If you hold down the digits will continue to change. 4.You only need to do when you install the PMP-25 (or if you change the hook-up). ADJUSTMENTS SET POINT - HIGH: The HIGH relay will switch when the load is above the HIGH. SET POINT - LOW: The LOW relay will switch when the load is below the LOW.

Start-up Timer The Start-up Timer bypasses the Control during motor startup to avoid false trips because of current inrush. For convenience, the TIMING BEGINS WHEN THE MOTOR STARTS. The Start-up LED stays lit until the start-up period is over.
