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.

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 three­color 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

the following items to set up your meter:

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

• Thermocouple

• 1/8” flat blade screwdriver

Mount the Unit

1. Cut a panel opening using
the dimensions shown to
the right.

2. Position the unit in the
opening, making sure the
front bezel is flush with the
panel.

3. Install retaining clip on the
meter and tighten against

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.

AC Powered Unit 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)
80 mA (230 Vac line) 63 mA (230 Vac line)

In order to maintain the same degree of
protection as the AC units, always use a
Safety Agency Approval DC source with
the same Overvoltage Category and
Pollution Degree.
