Description

FUNCTIONS
Cycle Time and Signal Rescaling
The cycle time is preset. An input signal is needed to control the output of the unit.
CAUTION: Adjustment of the cycle time and signal rescaling is possible using VR1 and VR2 but is not normally required. Incorrect settings of these controls can cause an overload condition, failure and permanent damage.
DO NOT ATTEMPT TO ADJUST THESE CONTROLS WITHOUT REFERENCE TO THE SUPPLIER/MANUFACTURER.
Manual Override
The PR1 controller is supplied preset to the auto ‘A’ position. It is possible to manually override the input signal by placing the J1 jumper plug in the ‘M’ position. With the jumper in the ‘M’ position the load will be 100% ON. The output load can be adjusted downwards using the signal rescaling facility (see above section).
Over temperature protection
An electronic thermal cut-out is fitted to heatsink to protect against over temperature. The PR1 regulator will switch off the load if the Heatsink temperature exceeds 90°C. once the heatsink temperature is below 85°C the unit should switch back on. Under normal operating the heatsink should not exceed 90°C, but may occur if the ambient temperature exceeds 40°C.

Features
 2.5kW, 3kW and 4 kW models available
 Integral heat sink for maximum power capability.
 2.5 and 3kW heatsink length = 50mm
 4kW heatsink length = 75mm
 Simple DIN Rail or Panel mounting
 LED power level indication
 Over temperature protection with auto shutdown and reset

Applications
Suitable for electric heater batteries, ceiling or radiant heating, hot water tanks, heating cable, furnace, ovens and plastic processing equipment.
