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 Indication On indicating controls, the display is not illuminated. Probable Cause(s) Corrective Action • Power supply switch off. • Turn switch on. • Fuse blown. • Replace fuse (check cause of failure). • Breaker tripped. • Reset breaker (check cause of failure). • Safety interlock door switch activated. • Close door. • Separate system limit control latched. • Reset limit controller. • Wiring incorrect or open. • Check wiring. • Power supply voltage incorrect.
Indication Probable Cause(s) Corrective Action Troubleshooting RTD inputs Temperature reading is in• Calibration offset incorrect (tactile correct, showing a sensor er- models only). ror, [Er;In] , or LOAD LED • Settings for degree C or F is incorrect. is switching at the wrong temperature. Check calibration offset Check model part number for degree C or F. If model has Increment/Decrement keys then C/F setting is adjustable. • Sensor or controller may be bad. Sensor 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, on rotary-knob models. • Front panel key on Push for Set Point or Push for Process options. • No operator interface on fixed set point models.
