INTRODUCTION

The Model 122 is a multipurpose, easy to use pulse rate/totalizer ideal for flow rate, total, and control applications. It accepts pulse (e.g. ±40 mV to ±8 V), square wave (0-5 V, 0-12 V, or 0-24 V), open collector, NPN, PNP, TTL or switch contact signals. Three of the front panel buttons can be custom-programmed for specific operation. The basic model includes an isolated 24 VDC transmitter power supply that can be used to power the input transmitter or other devices.

INSTALLATION

There is no need to remove the meter from its case to complete the installation, wiring, and setup of the meter for most applications. Instructions are provided for changing the transmitter power supply to output 5 or 10 VDC instead of 24 VDC, see page 15.

Unpacking

Remove the meter from box. Inspect the packaging and contents for damage. Report damages, if any, to the carrier.

If any part is missing or the meter malfunctions, please contact your supplier or the factory for assistance.

Panel Mounting Instructions

• Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x 45 mm). Refer to Figure 1 for more details.

• Clearance: allow at least 6.0" (152 mm) behind the panel for wiring.

• Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).

Recommended minimum panel thickness to maintain Type 4X rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.

• Remove the two mounting brackets provided with the meter (back-off the two screws so that there is ¼" (6.4 mm) or less through the bracket. Slide the bracket toward the front of the case and remove).

• Insert meter into the panel cutout.

• Install mounting brackets and tighten the screws against the panel. To

achieve a proper seal, tighten the mounting bracket screws evenly until meter is snug to the panel along its short side. DO NOT OVER TIGHTEN, as the rear of the panel may be damaged.

Transmitter Supply Voltage Selection (P+, P-)

All meters are shipped from the factory configured to provide 24 VDC power for the transmitter or sensor.

If the transmitter requires 5 or 10 VDC excitation, the internal jumper J4 must be configured accordingly.

To access the voltage selection jumper:

1. Remove all the connectors.

2. Unscrew the back cover.

3. Slide the back cover about 1 inch.

4. Configure the J4 jumper, located behind the input signal connector, for the desired excitation voltage as shown.

Connections

All connections are made to removable screw terminal connectors located at the rear of the meter.

Use copper wire with 60°C or 60/75°C insulation for all line voltage connections. Observe all safety regulations. Electrical wiring should be performed in accordance with all applicable national, state,
