TABLE 2-4. DIAGNOSTIC CONTROLS AND INDICATORS (continued)
CONTROL OR INDICATOR
I/O INTERFACE MODULE
HEARTBEAT (green LED)
This indicator is normally blinking on and off when DC power
has been applied to the module. It is also normally blinking
when the generator set is operating (engine running) and the
module is functioning properly. If the indicator is either steady-
state lit or steady-state off, but the CIM has been turned on and
the engine is operating, this is an indication that there is a
problem in the I/O interface module.
DIP Switch Assembly (8 positions)
These switches define the configuration of the generator set for
the CIM. The generator set configuration is defined in two
ways: its output power (kW) rating and its frequency rating.
These switches must be set to a specified configuration prior to
the module's use in the generator set. Unless these switches are
properly set (and remain so), the generator set can experience a
malfunction. For the MEP-806B, all switches are set to OFF.
For the MEP-816B, Switch 5 is set to ON and all the other
switches to OFF. (Ref Figure 4-31)
SECTION II. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
To ensure the generator set is ready for operation at all times, it must be inspected so that defects can be
discovered and corrected before they result in serious damage or failure.
Before Operation. Always keep in mind the CAUTIONS and WARNINGS. Perform Before (B) PMCS.
During Operation. Always keep in mind the CAUTIONS and WARNINGS. Perform During (D) PMCS.
After Operation. Perform After (A) PMCS.
If the Equipment Fails. If the equipment does not perform as required, refer to Chapter 3, Section II under
Troubleshooting for possible problems. The Symptom Index is provided as a guide for troubleshooting
procedures. Report any malfunctions or failures on DA Form 2404 (refer to DA PAM 738-750).
For general location of items to be inspected in Table 2-5, refer to Figures 1-30
Purpose of PMCS Table. PMCS, Table 2-5, lists inspections and care of equipment required to keep the
generator set in good operating condition.
Purpose of Service Intervals. The interval column of the PMCS table indicates when to perform a certain
check or service.
Special Instructions. The following guidelines are provided to help classify leaks observed while
Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
