CHAPTER OBJECTIVES
This chapter describes the steps necessary to ensure proper
start-up of the SMP-3 overload relay. The information
contained in the previous chapters must be read and understood
before proceeding.
IMPORTANT: Before start-up, the SMP-3 overload relay
should be configured and wired per the descriptions provided in
Chapter 3. The only programmable parameter of the SMP-3 is
the Logic Mask parameter. Refer to Chapter 8 for
programming instructions to alter the default value (unmasked)
of the logic mask parameter.
IMPORTANT: Refer to Chapter 9 for fault code information.
ATTENTION: To avoid electric shock hazard or
damage to equipment, only qualified personnel
should perform the following procedure.
Thoroughly read and understand the procedure
before beginning. If an event does occur while
performing this procedure, DO NOT PROCEED.
Remove power by opening the branch disconnect
device and correct the malfunction before
continuing.
START-UP PROCEDURE
The following start-up procedure is written for SMP-3
applications with Human Interface Modules. For application
without HIMs, disregard steps 5 and 6.
INITIAL OPERATIONS - MOTOR CONNECTED
❏ 1. Verify that the AC line power at the disconnect device is
within the rated value for the SMP-3 overload relay.
❏ 2. Disconnect and lockout all incoming power to the SMP-3
overload relay, including incoming AC power to
terminals L1, L2, and L3. Verify that the wiring is
connected to the proper terminals, with the proper wire
gauge and type of wire and that the proper short circuit
protection is used.
❏ 3. Verify that the SMP-3 outputs are in a de-energized state
before applying power.
POWER APPLIED – MOTOR CONNECTED
❏ 4. When power is first applied to the SMP-3 overload relay,
the green “Power” LED will turn ON. Also, an audible
click will sound indicating that the trip relay has closed.
❏ 5. In addition, when power is applied to the SMP-3
overload relay, the following information will be
momentarily displayed on the HIM:
