Commissioning Using Shc1 Handheld Interrogator; Introduction; First Time Switch On - Honeywell Searchpoint Optima Plus Operating Instructions Manual

MAN0905_Issue 7_07/17
9. Commissioning using SHC1
Read this chapter if the SHC1 Handheld Interrogator is being used to communicate
with Searchpoint Optima Plus.
Note: The instructions that follow assume that the SHC1 is switched on, in Optima+ mode, in the Main
Menu. See Chapter 8 "Use of the SHC1 Handheld Interrogator" for details.

9.1 Introduction

This chapter explains several operations that may be required during commissioning. Only First Time Switch
On is mandatory; Test 4-20 mA Loop Integrity is recommended. The instructions assume that the SHC1 is
switched on, in Optima+ mode, in the Main Menu. See Chapter 8 "Use of the SHC1 Handheld Interrogator"
for details.

First Time Switch On

Clear Faults or Warnings
Fix the 4-20 mA Output
Test 4-20 mA Loop Integrity
Caution: After changing any parameter, poll the Searchpoint Optima Plus and verify that the received
value is correct.
9.2 First Time Switch On
Note: Searchpoint Optima Plus is supplied calibrated and ready for use. It does not require calibration
during commissioning.
Note: During commissioning the 4-20 mA output can be monitored either at the control room or locally
with a multimeter. When connecting or disconnecting a multimeter, power off the Searchpoint Optima Plus,
otherwise the unit will indicate a latched warning that the 4-20 mA loop was broken. If this occurs it can be
cleared using the SHC1 Handheld Interrogator.
1. Before applying power to the unit, ensure that the field wiring is correct and all electrical connections
are in accordance with Section 4.
2. Apply power. Check that the supply voltage to the Searchpoint Optima Plus is between 18 and 32 V.
3. Monitor the 4-20 mA output during the start up sequence, which should be as follows: -
Note: If gas is present, the unit will indicate a gas reading.
