CHAPTER 10:
TROUBLE SHOOTING GUIDE
10.1 Introduction
This troubleshooting guide is intended to aid service/maintenance personnel in isolating the cause of a
fault in a Modulex Boiler. In the event of an operational failure, the controller used with Modulex boilers
will display a code to indicate the failure type. Troubleshooting procedures are presented in tabular form
on the following pages. The 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 Modulex Boiler, proceed as follows to isolate and correct the fault:
1. Observe the fault code (
E1
,
E2
,
E3
, etc.) displayed in the controller display (
Figure 9-1
).
2. Refer to the
Fault Indication
column in Troubleshooting Tables, which follow, 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 corrected.
6.
Table 9-2
, found at the end of this section, contains additional troubleshooting information which may
apply when no fault code is displayed.
NOTE
If the fault cannot be corrected using the information provided in the
Troubleshooting Tables, contact your local AERCO Representative.
