7.12 CONNECTOR BOARD
Procedure:
1. Turn OFF power, and shut off water supply. Follow
lock-out/tag-out procedures.
2. Remove lower shroud.
3. Remove control box cover.
4. Remove connectors from board.
5. Remove thermocouple wires.
6. Remove board.
7. Install new board by following the steps outlined
above in reverse order.
NOTE: When installing thermocouple wires, white
goes to + and red goes to -.
NOTE: The new connector board is supplied with
thermocouple calibration data. This data must be
entered via the Service Mode. Select Calibration,
and menu selection RESTORE. Refer to
SECTION 2, SERVICE MODE,
for complete
procedure.
NOTE: The concentration monitor must be
calibrated after board replacement.
7.13 CONTROL BOARD
Procedure:
1. Turn OFF power, and shut off water supply. Follow
lock-out/tag-out procedures.
2. Remove connectors from rear of control.
3. Remove standoffs at each jack using a 3/16" nut
driver.
4. Remove plastic cover.
5. Remove J6 and J7 ribbon connector (from Touch
Pad).
6. Remove four screws holding sheet metal/board
assembly to plastic panel.
7. Gently pick up sheet metal/board assembly and
slide ribbon cables free.
CAUTION – POSSIBLE EQUIPMENT
DAMAGE HAZARD: Use care when picking
up the sheet metal/board assembly,
because the display and printer cables are still
connected under the board.
8. Tilt sheet metal/board assembly up and disconnect
display cable first; then disconnect printer cable.
9. Remove sheet metal/board assembly from unit.
10. Remove board from sheet metal housing.
11. Prepare replacement board as follows:
a. New boards are unprogrammed. Either a
new-programmed chip set must be installed,
or chip set from original board must be
installed. New chip sets are marked U5 and
U22; however, original board chip sets may
not be so marked. U5 must be installed in U5
socket and U22 must be installed in U22
socket.
NOTE: The dot on the chip must line up with the
arrow in the socket.
Use a PLC chip puller (STERIS P 764326-559)
to remove chips. If this tool is not available, a
0.050" Allen wrench or similar device can be
used to gently pry up chip from socket.
b. Remove resistors R55 and R56 from the
new board. These are located next to the J9
connector. DO NOT REMOVE THE R54
RESISTOR. R55 and R56 resistors must be
removed in order to clear housing re-
installed later.
c.
Check dip switch settings on new board
and adjust so they match old board.
12. Install new board onto sheet metal housing.
13. Slide sheet metal/board assembly in place,
connecting printer connector first, then display
connector.
NOTE: The display cable is not keyed. If not sure
as to the proper positioning of the connector, look
at both connectors on the cable. Pin 1 of the
connector is indicated by an arrow. The Pin 1
designation on the display board can be seen
easily so that the display end of the cable can be
matched up easily. On the control board, Pin 1
designation is not seen easily; however, the back
side of the pins can be seen. Pin 1 has a square
cross-section, and therefore the Pin 1 of the
connector must be aligned with the pin with the
square cross-section.
14. Complete installation by following steps outlined
above in reverse order.
15. Perform a burn-in and calibration of transducer,
thermocouples, concentration monitor and UV
system before placing unit back into service.
7.14 PROGRAM CHIP CHANGE
Equipment, Fixtures, Special Tools:
1. Wrist strap.
2. PLC puller (P-764326-559 or equivalent).
