2.1 OVERVIEW
The operator interface of the BMS-2000 consists of two components:
• Heated, Back-lit LCD Alphanumeric Display
• 9-Key Membrane Keypad
OPERATION
Keypad functions:
•
START initiates the automatic ignition sequence of the pilot and BMS. Once the pilot flame is
proven, the BMS will continue into NORMAL OPERATION.
Note:
the BMS display must read “CLEAR TO START” in order to initiate startup sequence.
•
STOP cancels the ignition sequence and / or shutdown the operation of the BMS and pilot
by closing all fuel train valves and extinguishing the pilot flame. A shutdown reading
of “LOCAL MANUAL S/D” will be displayed on BMS display page 1, indicating the STOP
button has been pressed.
•
ACK clears any active shutdowns displayed on BMS display page 1. This key also acknowledges
passwords and selects items in the calibration and configuration menus for adjustment.
Note:
active shutdowns will only be cleared from the display
if they have been cleared in the
field and a safe condition exists
. If the ACK button is pressed and a shutdown has not
been field-cleared, a
*
symbol will appear beside the shutdown, indicating that it has
been acknowledged by the operator, but the error still exists in the field.
