5.0 PROCEDURE

5.1 Operate the Stack Monitoring Cabinet

NOTE - Activity Levels of Section 5.1 may be performed as directed by Shift Manager.

- Switching or shutting down Exhaust Fans will shut down the operating sample

pump and activate alarms (Low Beta Sample Flow, Low Record Sample Flow,

Pump #1 Failure and #2 Failure). Vacuum pumps will not start unless alarms

(Low Beta Sample Flow, Low Record Sample Flow, Pump #1 Failure and #2

Failure) have been cleared.

- Stack Monitoring cabinet K1-ENCL-400 is powered from distribution panel

A242-DP-L, by way of MCC-2 Compartment A3.

- When starting sample pumps flow will normally stabilize in 1-3 minutes.

Initial Start Up of K1-ENCL-400 Stack Monitoring Cabinet

5.1.1 CHECK enclosure K1-ENCL-400 is energized.

5.1.1.1 IF K1-ENCL-400 is not energized, PERFORM Electrical

Configuration per Checklist 1 AND

CONTINUE with this section.

5.1.2 OPEN door of K1-ENCL-400 stack sampling cabinet.

PRESS ALARM RESET push button PB-6.

NOTE - Placing selector switch SW-1 in the AUTO position for both the

LOCAL (K1-ENCL-400) and REMOTE (MCS) activates the

AUTOMATIC Sample Pump switch over functions. Either PB-1 or PB-2

buttons being latched in will defeat the auto pump switch.

- Placing selector switch SW-1 in the HAND position will not allow Sample

Pump switch over to occur.

5.1.6 CONFIRM selector switch SW-1 is in the AUTO position.

5.1.7 CONFIRM PB-1 and PB-2 are not LATCHED IN.

5.1.8 IF starting the sample pumps from the MCS, GO TO Section 5.2.
