11 Problem Solving
11.1Introduction
It is recommended to use the Honeywell Fixed Platform App as the primary troubleshooting tool.
Optionally, a HART handheld unit can be used to carry out diagnostics at the receiver (with rear cover open), or remotely,
or at a local HART junction box.
Refer to the troubleshooting table below for a list of problems, possible causes and remedy actions.
Note
The Searchline Excel detector continues to function as a gas detector while indicating Warning, although aspects of its
performance may be reduced. A Warning is an indication of a potential future problem.
CAUTION
!
1. Searchline Excel does not contain any user serviceable parts. Do not open the main enclosure. Doing so will
invalidate the warranty. Front enclosures may be opened only for advised repair maintenance by an authorized
and qualified person.
2. If a problem persists please contact Honeywell Analytics for advice, using the contact details given on the back
page.
Have the following information to hand:
- A description of the application and the problem, including the steps taken in attempt to resolve it
- The serial number of the Searchline Excel unit (see the label on the end cap)
- The service log downloaded from the Honeywell Fixed Platform App
- Installation checklist (refer to Chapter 7 Alignment and Commissioning)
If connected to Searchline Excel using HART, search for the following information by selecting Device Info from
the Device Setup menu:
- Dev id (unique Searchline Excel identification number)
- Fld dev rev (revision number of the HART EDD file)
- Software rev (Searchline Excel software revision number)
- Hardware rev (Searchline Excel hardware revision number)
3. Flamepaths are not to be repaired.
4. The equipment shall be connected to circuits providing Overvoltage Category II or better according to
IEC/EN 606641.
5. To minimize the risk of electrostatic charge, provisions shall be made for an adequate grounding of the
equipment, including accessories (e.g., sunshade). Equipment shall be installed in a manner so that accidental
discharge shall not occur.
CAUTION
!
Some types of faults and warnings will latch the 420 mA output and need to be cleared by a Reset, which will
clear latched events. Faults and warnings will fail to clear if they are still active.
