Electronic Modules; Options; Overload Ground Fault Module (Ogf); Phase Reversal Module (Prm) - Carrier VECTOR 6500 Operation & Service Manual

2.6 ELECTRONIC MODULES

2.6.1 Overload Ground Fault Module (OGF)

Figure 2−11 OGF Module
The OGF, see Figure 2−11, is located in the control box
(see Figure 2−5). The module has two electrical safety
features which are active in both Engine and Standby
Operation:
1. Overload protection.
2. Ground Fault (Leakage).
In each case, an "A100 - "OVERLOAD GROUND
FAULT" alarm is activated and the unit shuts down.
When ground leakage is detected, the red LED on the
OGF module will be on continuously.

2.6.2 Phase Reversal Module (PRM)

Figure 2−12 PRM Module
The PRM, Figure 2−12, is located in the control box (see
Figure 2−5). In Standby Operation, the phase reversal
module checks the electrical phase and reverses if
necessary.

2.7 OPTIONS

2.7.1 Light Bar
The Light Bar is an external indicator light which can be
seen in the driver's rear view mirror from the cab of the
tractor. The green LED indicates "STATUS OK". The
9
amber LED indicates "CHECK UNIT". The amber light is
illuminated when the microprocessor illuminates the
fault light. Alarms can be read on the microprocessor
display.

2.7.2 Remote Switch(es)
The unit is provisioned to connect remote switches (DS
or REMS) directly to the microprocessor.
S Two types of switches may be used:
1. A switch with contacts that are open when the
switch is activated.
2. A switch with contacts that are closed when the
switch is activated.
S Four Configurations are available for each switch.
1. Activate an alarm only while the switch is activated.
2. Activate an alarm and shut the unit down while the
switch is activated. The unit will remain shut down for
a minimum of 3 minutes under this setting.
3. Activate the alarm and bring the engine into low
speed while the switch is activated.
4. Record the switch activation in the DataLink data
recorder.
S If configured to shut the unit down or bring the engine
to low speed an additional choice will be available.
The additional choice allows the unit to be set so that
the configured action will always take place OR the
configured action will only take place when the ambi-
ent temperature is below a certain temperature. For
example, if the shutdown/low speed temperature
choice is set to 77°F (25°C) the unit will only shut-
down/go to low speed if the ambient temperature is
below 77°F (25°C).
S Additionally a Functional Parameter "override" set-
ting will be available for each switch configured to
shut the unit down. The Functional Parameter may be
set to "YES" or "NO". If the Parameter is set to "NO"
the configured action will not be overridden. If the
Parameter is set to "YES", the alarm will be activated
but the unit will not shutdown.
