PERMANENT BURN-IN OF DIPSWITCH FUNCTIONS
The EP Programmer modules have a set of six (6) dipswitches on the side of the programmer to mod-
ify various functions associated with the operation of the programmer (e.g. purge timing, prove 3-P
circuit open to start, etc.). THESE FUNCTIONS BECOME PERMANENT AFTER THE CON-
TROL HAS BEEN POWERED FOR EIGHT (8) HOURS .
*
After this burn-in period, changing
position of the dipswitches will not change the operation of the programmer.
Note: The function of dipswitch 1 is not stored.
The user can bypass the burn-in period via the ED510 display module. Use the SCROLL and MODE
key to select the “Programmer Set-Up” Sub-Menu (Refer to bulletin ED-5101) and then the
SCROLL key to display the prompt:
PRESS RESET TO
ACCEPT SETTINGS
Press the Reset key at this prompt and the screen will display:
YOU AGREED TO
ACCEPT SETTINGS
After the above key sequence is completed, changing the position of the dipswitches will not change
the operation of the programmer.
PROGRAMMING THE EP163 PROGRAMMER MODULE
The EP163 Programmer Module provides a number of operational characteristics that are selected
via the ED510 Keypad/Display rather than by dipswitch selection. The following is a list of the pro-
grammable functions associated with the EP163 Programmer Module:
— Selectable purge (selectable from 6 seconds to 40 seconds in 2 second increments - default
setting is 40 seconds).
— Prove the operation of the 3-P Running Interlock Circuit.
— Prove the operation of the High Fire Purge Interlock (D-8).
— Prove the operation of the Low Fire Start Interlock (M-D).
— Selectable timings on terminals 5 and 6 during Pilot Trial For Ignition (PTFI).
— Selectable timings on terminals 5 and 6 during Main Trial For Ignition (MTFI).
— Selectable Post Purge Timing of 1 or 15 seconds.
MODIFYING THE PROGRAMMER
1.
Insert the EP163 programmer module into the EB700 chassis and connect the ED510 Keypad/
Display.
2.
Open the operating control (L1-13) circuit. The EP163 cannot be modified unless the operating
control is open.
3.
The PROGRAM SETUP sub-menu will be used to display the programmable functions. Press
the SCRL key until the PROGRAM SETUP sub-menu is displayed.
4. Press the MODE key to enter the PROGRAM SETUP sub-menu. The SCRL key will advance
through the selections in the sub-menu. The first four items displayed in the sub-menu are PRO-
GRAMMER TYPE EP163, ENGR CODE, AMPLIFIER TYPE, and FFRT TIME 4 S. These
items are not programmable.
5. Press the SCRL key and the next item displayed (and first programmable item) is PURGE TIME
followed by the current setting (default setting = 40 seconds). The available purge timings are
from 6 to 40 seconds, in 2 second increments.
6. Press and hold the RESET button for 1 second to enter the “Modify” mode (providing the con-
trol was not in a lockout condition). After a 2-3 second delay, the control will display SCRL TO
MODIFY on the top line of the display (replacing STANDBY).

Programmer module EP163 has a fifty (50) hour burn-in period.
