Shunt Jumper-Controlled Options
Jumpers installed in the shunt-jumper socket JP1 on the
main logic board control the following options.
D
Extended Time Delays— DD-100-B
D
Plant
Exerciser— DD-23-C,
DD-23-D,
and
DD-23-G
D
Voltage/Frequency Sensing— DD-34-J
D
Phase Sequencer— DD-34-Z and DD-05-K
D
In-phase Monitor— DD-34-A
D
Off Delays
See Appendix B Figure B-9 to locate JP1.
See
Figure 4-15 to locate option shunt jumper locations on
JP1. Programming Index 11 displays installed control
options status as enabled or disabled. Figure 4-16
describes the options in Index 11.
To add/remove shunt-jumper controlled options:
1. Add/remove shunt-jumpers across the terminals
next to the name of the option on JP1 and shown in
Figure 4-15.
Do not remove the MANUAL
OVERRIDE jumper.
2. Go to Index 20 and press Menu Down and look for
OPTIONS LOCK? NO. If the question does not
appear, the options are locked. Go to step 3.
Otherwise, lock the options:
a. Answer the question with YES then ENTER
.
The
controller
briefly
displays
ENTRY
ACCEPTED.
b. Press RESET MENU and then ENTER to store
the setpoints. The controller briefly displays
STORE SET--POINTS. The options will remain
locked when the controller powers back up the
next time.
3. Power down the controller by disconnecting the
inline disconnect plug P1.
4. Wait a minimum of 1 minute then reconnect plug P1
to power up the controller.
5. Check Index 11. YES should appear only after the
Index 11 listing of all options with installed shunt
jumpers.
To troubleshoot shunt jumper-controlled options see
Figure 4-17 or Figure 4-18.
NOTE
When the options are not locked the controller does not
check JP1 upon powerup to determine option status, but
rather reads the setpoints stored before power was
interrupted.

Control Option
Description
INPHASE MON
Shows Inphase Monitor enabled (Yes) or disabled (No).
PHA SEQ/LOSS
Shows Source-Phase-Sequence enabled (YES) or disabled (NO). (Transfer Switch contactor lug
connections must be properly phased ABC in order for the source to be acceptable).
NORM & EMER
Shows sensing enabled (YES) or disabled (NO) of overvoltage, undervoltage, overfrequency,
underfrequency for both the normal source and the emergency source.
PLANT EXER
Shows generator set/system exerciser enabled (YES) or disabled (NO).
TD EXTENDED
Shows extended time delay enabled (YES) or disabled (NO).
MAN OVERRIDE
Shows manual override enabled (YES) or disabled (NO). Enabled manual override (YES) allows
automatic transfer to an available source when connected source fails. Transfer time delays will
be bypassed. Disabled manual override (NO) causes the logic board to wait for manual operation.
The logic board will not automatically seek available source.
OFF DELAYS
Shows time delay off to normal and off to emergency are enabled (YES) or disabled (NO).
