TROUBLESHOOTING
9.1 INTRODUCTION
This section is intended to aid service/maintenance personnel in isolating the cause of a fault in
your Benchmark boiler. The troubleshooting procedures below are presented in tabular form on
the following pages. These tables are comprised of three columns labeled: Fault Indication,
Probable Cause and Corrective Action. The numbered items in the Probable Cause and
Corrective Action columns correspond to each other. For example, Probable Cause No. 1
corresponds to Corrective Action No. 1, etc.
When a fault occurs in the unit, proceed as follows to isolate and correct the fault:
Fault Correction Instructions
1. Observe the fault messages displayed on the Edge [i] Controller.
2. Refer to the Fault Indication column in Troubleshooting Table 10-1, below, and locate the Fault that
best describes the existing conditions.
3. Proceed to the Probable Cause column and start with the first item (1) listed for the Fault Indication.
4. Perform the checks and procedures listed in the Corrective Action column for the first Probable
Cause candidate.
5. Continue checking each additional Probable Cause for the existing fault until the fault is corrected.
6. Section 9-2 contains additional troubleshooting information that may apply to situations in which no
fault message is displayed.
If the fault cannot be corrected using the information provided in the Troubleshooting Tables,
contact your local AERCO Representative.
