View Addressable Sensor Data
This menu allows the veiwing of data received from an indivdual CAN sensor for upto 24 hours. Use the UP
(1) and DOWN (5) buttons to choose the sensor channel to be displayed. The data displayed is as follows:
Addr 00
Timeout in 00sec Lowest=00
ST1 00 ST2 00 Rstat 00
Pressing
SELECT (3)
again exits this menu.

Unlatched Alarms
Each sensor channel can have latched or unlatched alarms. This menu shows the current state of this feature
and can be toggled by pressing
+ (4)
or
– (2)
. The sensor channel is selected by using the UP (1) and
DOWN (5) buttons. Unlatching alarms will clear automatically when the gas level is below the alarm point.
Pressing
SELECT (3)
will exit this menu.

Event to relay 64
Each event which is stored in the 99 event log can also activate a relay. Use this menu to choose which relay.
Use
UP (1)
and
DOWN (5)
to choose the event (which is displayed on the LCD) and then use
+ (4)
and
–
(2)
to choose which of the 64 relays to drive. The default is not to drive any relays.
Also, each event can drive the first 16 relays as a pattern which is ORed in. This means that patterns which
overlap will mix together and effectively create a group action. Each event has its own individual pattern of 16
bits, where 1 = relay active and these can be edited using the display where a cursor is moved using
+ (4)
and
– (2)
buttons and
UP (1)
and
DOWN (5)
will set one and zero in the cursor position.
gfedcba987654321 represent the 16 relays. 1 = relay 1 and g = relay 16.
With so many events needing patterns, it is usual to download these patterns from a PC using menu number
29. Note: that if a relay is normally energised (menu 36) then the effect of a 1 will turn the relay off. Pressing
SELECT (3) will exit this menu.
Additionally, pattern 8765 321 can be redirected to 7 relays on the 8 way relay card. The fault relay 4 always
remains as Fault but the remaining relays are assigned as remote relays 123 5678 respectively. This feature
eliminates the need to fit a remote relay PCB for smaller installations.
Pressing
SELECT (3)
will exit this menu.
A second alternative relay option is available using the + and – buttons. Here, the 8 local relays Low, High,
Overange, Flt, Opt1, Opt2, Opt3, Opt4 can be diverted to drive remote relays 1,2,3,4,5,6,7,8.

Relay off Timers
Each of the 8 relays on the main PCB can have delayed de-energise times and this menu allows you to set the
delay in seconds. Use
UP (1)
and
DOWN (5)
to select which of the 8 relays to set and then
+ (4)
and
– (2)
to alter the time. The minimum time is 1 second and the maximum is 255 seconds. This feature is extended to
the first 16 relays which have a pattern output created by an event. SELECT (3) will exit this menu.

Channel Voting
There are 4 groups of sensors which drive 4 option (voting) relays. This menu allows you to set how many
alarms in a group are required before its relay will energise and then which sensors are in the group. Sensors
can be in any group or multiple groups or no groups.
The first part of this menu enables you to set the number of alarms by using
+ (4)
and
– (2)
buttons. The
maximum is 10 alarms. Use the
UP (1)
and
DOWN (5)
buttons to change the group number being set.
Pressing
SELECT (3)
goes to the second part of this menu this sets which group the 4-20 direct channels are
in followed by the addressable channels. The
+ (4)
and
– (2)
changes the group and
UP (1)
and
DOWN
(5)
changes the channel.
If a sensor channel is in group 1 the display would be
1 - - - - - - -
If a sensor channel is in group 3 the display would be
- - 3 - - - - -
If a sensor channel is in group 1 and 3 the display would be
1 - 3 - - - - -
If a sensor channel is in group 1, 2, 3 and 7 the display would be 1 2 3 - - - 7 -
If a sensor channel is in no groups the display would be
- - - - - - - -
Pressing
SELECT (3)
will exit this menu.
