High Temp Alarm / HAt
Low Temp Alarm / Lat
High temperature alarm and low temperature alarm allow for individual alarm
setpoints . Both are absolute values . By setting HAt to the maximum value and LAt
to the minimum value, alarms will be deactivated .

High Alarm Delay / Htd
Low Alarm Delay / Ltd
These parameters express the number of minutes to wait before sounding an
alarm once the High/Low Temp Alarm temperature is reached . Immediately prior
to the alarm sounding, another check of the temperature is made to see if the
temperature is still in the alarm zone; if it is not, the then the alarm is not sounded .
In most situations, the Low Alarm Delay will be set to 0 to warn about too low a
temperature immediately .
Pulldown Delay / Pdd
Normally, it is not necessary or desirable to sound an alarm during a pull down
(the initial phase of reaching the desired temperature) .
This parameter prevents
the High Temp Alarm HAt sounding during pull down and after a defrost for the
number of minutes set for the parameter .
NOTE:
It does not apply to the Low Temp Alarm LAt.
Door Open Delay / dod
It is possible to indicate to customers that a door has accidentally been left open .
This parameter sets the delay in minutes before the alarm sounds . This is useful in
environments where customers / users may hold the door open while making their
selection . If the door is closed again before the set number of minutes is reached,
the alarm does not sound .
NOTE:
A door sensor is required if this parameter is to be activated.
Alarm Buzzer Duration / Abd
The ERC 102 alarm sounds for 10 seconds, followed by silence for 50 seconds . One
alarm sequence therefore lasts 60 seconds . These values cannot be changed . This
parameter determines how long in minutes an audible alarm will continue while
there is still a reason to have an alarm . If set to 999, the alarm will continue to
sound until the reason for the alarm is cleared – for example the temperature has
dropped enough or the door closed . In some cases, it may be necessary for a user
or technician to take action in order to clear the alarm . If set to 0, the alarm will
never sound .
