Using This Quick Start Manual

Use this Quick Start Manual with your controller to make changes to the thermocouple type, decimal point, units, and to change the setpoints.

Features with are for the “B” version which has three- color programmable “Big” LED display - All segment characters shown are for the “B” version.

For detailed instructions, refer to the appropriate section in the Operator’s Manual.

Before You Begin

In addition to the meter and the related parts, you will need the following items to set up your meter:

•ac power, as listed on meter’s ID/Power Label

•Thermocouple

•1/8” flat blade screwdriver

Safety Consideration

This device is marked with the international Caution symbol.

The instrument is a panel mount device protected in accordance with EN61010-1 (Safety requirements for electrical equipment for measurement, control, and laboratory standard). Remember that the unit has no power-on switch. Building installation should include a switch or circuit-breaker that must be compliant to IEC 947-1 and 947-3.

Wiring

Warning: Do not connect AC power to your device until you have completed all input and output connections. This device must only be installed by a specially trained electrician with corresponding qualifications. Failure to follow all instructions and warnings may result in injury!

1.Remove the panel at the back of the unit.

2.Locate the TB1 connector.

3.Insert the correct wire in each terminal as shown in the following figure and tighten the lockdown screws.

4.Tug gently on the wires to verify the connections.

External Fuse Required:

Time-delay, UL 248-14 listed	Time-lag, IEC 127-3 recognized
175 mA (115 Vac line)	125 mA (115 Vac line)

Thermocouple Wire Connection

1.Connect positive (+) lead of thermocouple.

2.Connect negative (-) lead of thermocouple.

Note: The negative lead is red.

Example hook up for AC Load

Alarm 1 (Setpoint) Hook-up

1.Connect a jumper from ac Line to Relay 1 Common (Terminal 3).

2.Connect Relay 1 Normally Open (Terminal 1) to External Alarm ac Line.

3.Connect External Alarm to ac Neutral.

Alarm 2 (Setpoint) Hook up

1.Connect a jumper from ac Line to Relay 2 Common (Terminal 6).

2.Connect Relay 2 Normally Open (Terminal 4) to External Alarm ac Line.

3.Connect External Alarm to ac Neutral.

Analog Output Wiring for 4 - 20 mA Current

1.Connect Positive Lead to Terminal 11.

2.Connect Negative Lead to Terminal 12.

For 0 -10 Voltage

1.Connect Positive Lead to Terminal 10.

2.Connect Negative Lead to Terminal 12.

SAFETY:

•Do not exceed voltage rating on the label located on the top of the instrument housing.

•Always disconnect power before changing signal and power connections.

•Do not use this instrument on a work bench without its case for safety reasons.

•Do not operate this instrument in flammable or explosive atmospheres.

•Do not expose this instrument to rain or moisture.

EMC:

• Whenever EMC is an issue, always use shielded cables.

• Never run signal and power wires in the same conduit.
