Quick "How To" Guide
1. Route monitored wire through aperture, mount using
two screws and mounting feet.
2. Connect 0-5Hz/0-10Hz output to PLC (or other meter
device) using 14-18 AWG copper wires. Ensure
polarity is correct for Sink or Source connection (see
"Output Wiring" section) and programmed PLC
settings match recommended bandwiths.
3. Power supply must be 24VAC/VDC. Connect using 14 -
18 AWG copper wires. Power LED should be on
whenever power is connected to the unit.
4. Choose input range by positioning the Range Jumper.
Facing the 3-pin jumper, position jumper over top two
pins for High range, bottom two pins for Mid range,
and no jumper for Low range.
5. With current flowing through unit, check for proper
operation by confirming frequency output is propor-
tion to input current.
