GENERAL
These operating instructions refer to the facilities available for general
operation and interrogation of the system without the Engineering Key
fitted.
Facilities that may effect the way the system operates are covered in
the Engineer's Operating Instructions Chapter 7 which refers to facilities
available when the Engineering Key is fitted.USER OPERATING ROUTINES
Depending upon which keypad function push-buttons are operated,
the following user operating routines may be performed:
Channel reset.
Channel select.
View alarm levels.
Catalytic sensor current check.
Sensor signal monitoring.
Accept an update alarm.
View clock/calendar.
Initiate a maintenance record printout.
Channel reset and select are performed by the channel card RESET/
SELECT push-button while the remaining functions are performed,
when a channel control card is selected using the Engineering Card
push-button controls.
Only one channel card can be selected at any one time and while
selected its microprocessor monitors the Engineering Card pushbutton functions to determine what action should take place.CONTROL CARD
3.1 Reset
To reset a channel control card, briefly push and release its front panel
RESET/SELECT push-button.
This will:
a. Reset all latched and non-active alarms associated with the control
card.
b. Cancel all latched and non-active warning messages.
c. Reset the peak reading display.
d. Acknowledge an update condition should one be present.
3.2 Reset TWA Calculations and Max/Min Values
The max/min signal values, STEL and LTEL values, and time
calculations may be reset to zero by pushing and holding down the
required channel card RESET/SELECT push-button for approximately
five seconds. During this period the selected icon will start to flash on
and off, and when the flashing stops the reset is complete.
3.3 Select
To select a channel card for operations controlled from the Engineering
Card, push and hold the required channel card RESET/SELECT pushbutton for approximately 1.5 seconds until the icon display changes
from the normal display to the selected display as shown below:
Normal Operation Selected
3.4 Deselect
To deselect a selected channel card, briefly push its front panel
RESET/SELECT push-button.
The channel card will be deselected and any user operations in
progress which have not been confirmed will be cancelled. It should be
noted that the channel card will not be reset unless the RESET/
SELECT push-button is again momentarily pushed.
