6.4 Control Board Jumpers
In the upper left hand corner of the control board there
are eight two-pin jumpers labeled JP1 through JP8. Only
six of the eight jumper pairs are utilized. Pairs JP7-JP8
are used for factory settings and testing. NOTE: Do
not install jumpers in the ON position on pairs JP7
through JP8. The jumper is a removable bridge that is
used to make or break continuity between two pins that
form a pair. When installed in the ON position, the jumper
is place on both pins of the pair and continuity between
the pins is established. When installed in the OFF posi-
tion, the jumper is removed or stored on a single pin and
continuity is broken. Jumper functions are as follows:
1. JP1 – Dryer Type
Jumper JP1 is used to select the dryer type configu-
ration. It is installed in the ON position for Blower
Purge dryer configuration.
2. JP2 – Energy Management
Jumper JP2 is installed in the ON position when an
Energy Management sensor is installed. The jumper
is installed in the OFF position when no Energy
Management sensor is installed.
3. JP3 – Dew Point Transmitter
Jumper JP3 is installed in the ON position when a
Dew Point Transmitter is installed. The jumper is
installed in the OFF position when no Dew Point
Transmitter is installed.
NOTE: "Energy Management" can co-exist with the
dew point transmitter option. Dryer control based
on the ENERGY MANAGEMENT or DEWPOINT
CONTROL is selected on Screen 1 of the Set Up
Mode.
If DEWPOINT CONTROL is not selected then the
dew point signal does not control the dryer cycle but
still serves a monitoring and alarm function.
4. JP4 – Cooling Cycle
Jumper JP4 is installed in the ON position to disable
the Cooling Cycle. The jumper is installed in the OFF
position to enable a Cooling Cycle.
5. JP5 – Switching Failure
Jumper JP5 is installed in the ON position to enable
Switching Failure. The jumper is installed in the OFF
position if Switching Failure is disabled.
6. JP6 – Common Alarm
Jumper JP6 is installed in the OFF position to en-
able both the dryer fault alarms and service alarms
to activate the common alarm. This is the default
configuration. Install jumper JP6 in the ON position
if the common alarm is to activated by a dryer fault
alarm only.
NOTE: Jumpers JP7 and JP8 are used by the fac-
tory during final inspection to download language
text and to enable 'factory' set-up screens.
