WARNING AND ALARM CIRCUIT MODIFICATIONS (continued)
2-7.1
Modification For Common Point Resetting (continued)
4.
Insert replacement lens into lens socket on front panel of module (except CD800X enclosure).
5.
Reinstall module in housing or enclosure.
6.
Mount RESET switch on enclosure door, housing panel, remote control console panel, or whenever
desired.
NOTE: J-W Conversion Kit #0023-4080 provides a pushbutton switch mounting in 5/8-inch-diameter
hole, RESET label, and 42-inch wiring harness. Lacking this, any SPST-NC momentary
contact switch will serve. (Figure 2-28.)
7.
Connect two wires from switch to RESET terminals on enclosure or housing terminal strip (CD800P:
Terminals TB-2, 8 and 9).
8.
Connect RESET terminals of all modules in parallel with RESET terminals of first module.
2-7. 2
MODIFICATION FOR AUTOMATIC RESET. Modify control unit printed circuit boards for automatic
resetting of warning and/or alarm circuitry after a circuit-triggering gas condition has cleared as
follows:
2-7. 2.1
To modify CD802 and CD832 control units for automatic resetting:
1.
Remove diodes from control unit printed circuit boards as follows:
a. For automatic resetting of warning circuitry only (retaining manual alarm circuitry resetting):
Clip leads of diode CR25 and remove diode.
b. For automatic resetting of alarm circuitry only (retaining manual warning circuitry resetting):
Clip leads of diodes CR21 and CR22 and remove diodes.
c. For automatic resetting of both warning and alarm circuitry: Clip leads of diodes CR25, CR21,
and CR22 and remove diodes.
2.
If both warning and alarm functions are modified for automatic resetting:
With fingers, grasp and withdraw RESET lens from socket and replace with unlabeled red lens
0104-6826. If manual resetting is retained for either warning or alarm circuitry, do not replace the
RESET lens.
