HIM INSTALLATION AND REMOVAL

Installation

The HIM can be used as a hand-held terminal or it can be
mounted on the front of an enclosure. The HIM connects to the
SMP-3 overload relay via a SCANport cable plugged into the
“COMM” port on the front of the SMP-3 overload relay.
Communication with any HIM that is plugged in to the SMP-3
overload relay is established when the SMP-3 overload relay is
energized.

The SMP-3 overload relay has one SCANport communication
port. This can be expanded to a maximum of two ports with a
splitter (Cat. No. 1202–SG2). Only one splitter may be used
and the total current draw of the two adapters must not exceed
200mA.

Removal

The HIM can be disconnected from the SMP-3 overload relay
in one of two ways:

A. Turn off outputs A and B (if ON), de-energize the SMP-3

overload relay, disconnect the HIM cable from the SMP-3
overload relay, and re-energize the SMP-3 overload relay.

B. Remove the HIM from the SMP-3 overload relay while the

SMP-3 overload relay is energized by masking out the
Logic Mask bit that identifies the adapter address of the
HIM. Refer to Chapter

8

for Logic Mask programming

instructions.

IMPORTANT: When the Logic Mask bit for an adapter is
changed from “1” to “0,” it disables all command functions for
the adapter except for the stop commands.

IMPORTANT: If any unmasked communication adapter is
disconnected from the SMP-3 overload relay while the SMP-3
overload relay is energized, the SMP-3 overload relay will
issue a “Comm Fault.”
