The Series 40M2 Digital Temperature Controller accepts a variety of inputs for temperature measurements and set points up to 999°F/537°C. Observing the current status of the controller is made easy with the 3-digit, multi-color LED display that has

alarm and output symbols. For added versatility, the temperature units can be eld selected for °F or °C. A ashing alarm informs users when the current temperature

exceeds preset limits. The On-Off/PID and PID with auto-tuning provide accurate and reliable control in complex applications. The Modbus used to communicate over a TTL/RS-485 interface. When programming multiple units, the 40X2-K programming key is available to reduce setup time.

INSTALLATION Note: Unit must be mounted away from vibration, impacts, water and corrosive gases.

• Cut hole in panel 2-51/64 x 1.9/64 in (71 x 29 mm).

• The thickness of the panel must be between 1/32 and 5/64 in (0.8 and 2.0 mm).

• Insert unit into hole from the front side of the panel.

• Slide the mounting bracket securely against the panel from the rear of the unit.

• Wiring diagram is displayed on top of the switch.

Avoid installing the temperature probe cables in close proximity of any power cables. Maximum cable length of 10 m (32.8 ft) for all cables, except for the PWM analog output

which is 1 m. A temperature offset adjustment may be made using the CA1 parameter. Connection methods include xed and plug-in screw terminal blocks for wires up to 14
