1 Overview Watlow's Series C family of basic temperature controllers* provide an economical controller solution for applications where simple on/off control is needed. These controllers are available with or without an operator interface and can be ordered in square 1/8th DIN panel mount, din rail mount, open board or potted module design configurations. Push-on, quick connect spade terminal or removable screw clamp style terminal block ordering options provide the electrical connections.

Troubleshooting On indicating controls, the display is not illuminated • Power supply switch off. • Fuse blown. • Breaker tripped. • Safety interlock door switch activated. • Separate system limit control latched. • Wiring incorrect or open. • Power supply voltage incorrect. • Defective controller. • Turn switch on. • Replace fuse (check cause of failure). • Reset breaker (check cause of failure). • Close door. • Reset limit controller. • Check wiring. • Verify input power • Repair or replace controller.
Indication Probable Cause(s) Corrective Action Troubleshooting RTD inputs Temperature reading is incor- • Sensor or controller may be bad. Sensor rect, showing a sensor error, connections may be bad. [Er;In] , or LOAD LED is switching at the wrong temperature. • Place a 110 ohm resistor across the sensor input terminals. The display should indicate 25°C (77°F). If it does, the controller is OK. Sensor or connections may be bad.
Specifications Controller • Microprocessor based, on-off control mode. • Nominal switching hysteresis, typically 1.7°C (3°F). • Input filter time: 1 second Operator Interface (model dependent) • Four digit , 7 segment LED displays, .28" high. • °F or °C indicator LED. • LOAD indicator LED. • Continuous turn, velocity sensitive rotary encoder for set point adjustment. • Front panel key on Push for Set Point or Push for Process options. • No operator interface on fixed set point models.
