PRO-TC

Temperature Controller

This quad channel thermocouple con-

troller is ideal for numerous industrial

temperature applications. It accepts di-

rect sensor input from all common ther-

mocouple types.

One of the key features of this controller

is its ability to average the inputs across

2, 3 or 4 temperature channels, and use

this averaged value for a display source

or for setpoint activation.

2.2 - Display brightness

To adjust the display brightness, press the and buttons together from the main display. BRI appears and toggles with the current setting. Use the and

buttons to adjust the LED backlight, and then press to nish.

2.3 - Up and down button shortcuts

Pressing the and buttons from the main operational display allows instant

access to a number of values held in the controller's memory. These variables will ap-

pear in the order shown in the table below, and will cycle continuously at each press

of the or button.

Press

reset to zero by pressing the and buttons at the same time while the variable

is being displayed.

3.2 - Analog input

See 3.1D

Wire the analog input module as shown, referring to the

product label. The unit accepts input from up to four ther-

mocouple sensors. (To use less than four sensors, select

your number of sensors in 6.2D.)

(see 3.7)

Note that you must start wiring from channel 1. (I.e. For 2 channels, use CH1–2, not CH3–4).

3.3 - Relay outputs

See 3.1A

If your controller has relay

outputs tted, wire them as

shown. Relays can be pro-

grammed to operate within

the total span range of the

controller.

Note that if you have activated the multiplex feature by setting your analog output source to MPX in 6.6B, then the 'Pk/Val' and 'Hold' pins will not perform the func-

tions described above. (See 5.4C for more information.)

3.7 - Power supply

See 3.1F

DO NOT attempt to wire your controller while the power is on. NEVER connect your low voltage controller to mains power.

Wire your controller for low or high voltage power supply, as show in the diagrams

below. Check the label on the unit against the colour of the connector:

› Orange =

High voltage (85–265V AC,

95–370V DC)

› Black =
