Push the Engineering Card ALARMS push-button for a sixth time and
TEST will be displayed on the message display. Initially the A1 level is
displayed on digital display and the A1 LED is illuminated.
Note: The TEST function automatically inhibits the control card to allow
a lamp test of the alarm LEDs and prevent accidental alarms
being generated. In order to test the relays and the FAULT LED,
the INHIBIT push-button must be used to set the control card into
the uninhibited state.
(12) Use the and push-buttons to raise or lower the simulated gas
level over a range of levels that includes the A1, A2, A3 and underrange
fault values. Check that the selected control card indicates the
simulated gas level on the analogue and digital display, and that the
appropriate alarm states are indicated on the LEDs.
(13) Push the Engineering Card ALARMS push-button for a seventh time
and TEST alternating with STEL will be displayed on the message
display and OFF will be displayed on digital display.
(14) If enabled, use the and push-buttons to switch the STEL alarm
between OFF and ON.
(15) Push the Engineering Card ALARMS push-button for a eighth time,
and TEST alternating with LTEL will be displayed on the message
display and OFF will be displayed on digital display.
(16) If enabled, use the and push-buttons to switch the LTEL alarm
between OFF and ON.
(17) Further pushes of the ALARMS push-button will scroll through the
alarm levels again. ie. A1, A2, A3, STEL, LTEL, TESTA1, A2, A3, TESTSTEL,
TESTLTEL.
Note: 1. A selected control card may be deselected while in the TEST
mode by pushing the selected control card front panel RESET/
SELECT push-button. The simulated gas level and relay
states will remain set allowing several control cards to be
tested simultaneously. When the control card is reselected
the card will return to the TEST mode.
2. If the inhibit is removed, the external relays will operate.
IMPORTANT
When the TEST mode is used, always ensure that the channel control
card is returned to the uninhibited state after the test.CATALYTIC SENSOR BRIDGE CURRENT
ADJUSTMENT
The operation associated with the BEAD mA push-button only applies
when a control card has been selected that is configured for a catalytic
input. The pressing of the push-button with other types of control cards
selected has no effect and a warning is displayed to this effect.
To enter the catalytic sensor bridge current operation, proceed as follows:
(1) Plug the Engineering Key into the Engineering Card front panel
socket and check that the Unlocked LED ( ) is illuminated.
(2) Push and hold the required control card RESET/SELECT pushbutton for approximately 1.5 seconds and check that the selected
control card indicates it has been selected by displaying the select
icon.
(3) Push the Engineering Card BEAD mA push-button and
check that the selected control card message display
shows mA and the digital display shows the actual bridge
current.
