5 Bargraph Display Scale
By pressing the

key, the bargraph display scale may be adjusted to
show the temperature range best suited to the particular installation. This
scale is also used for the “Plot display” (Ref. 3.6 Current Day Plot and 3.7
Plot History).
6 High Alarm Stage 1 temperature (-50°C to +50°C)
The Stage 1 alarm is a time / temperature related alarm. If the
maximum threshold is exceeded, a timer is initiated, and no further action is
taken at this time.
7 High Alarm Stage 1 Delay (1 – 99 min.)
After the maximum threshold has been exceeded (Ref. 4 above), the alarm
will not be triggered until the timer exceeds the time delay set here. If the
temperature drops below the threshold before the expiry of this delay, the
timer is reset. If following this the temperature rises above the threshold
again, the timer restarts from zero.
8 High Alarm Limit Stage 2 temperature (-50°C to +50°C)
If at any time this limit is exceeded the time delays will be overridden and the
alarm will trigger immediately.
9 Low Alarm
All the functions described in 6-8 above also apply to the low alarm.
