The Series 40T2 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 easier 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 Modbus 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. 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 AWG (2.5 mm

) and picoblade connector.

NOTICE

To reduce any electromagnetic interference, mount the power cables as far away as possible from the signal cables.

• Disconnect the power supply before carrying out any type of maintenance.

INITIAL SETUP

1. Install unit with the provided instructions above.

2. Electrically wire the device as described in the wiring section. A power-on self-test will begin once power is applied. This test will take a few seconds and the display will

switch off when it’s complete.

3. Congure the device as shown in the section SETTING CONFIGURATION PARAMETERS. The recommended parameters for rst time use are listed in the chart below:
