As previously mentioned, this cabinet is fi tted with a 3-pin socket on the cabinet to allow for connection to a building moni-
toring system (BMS), or to a phone dialer. A plug is also supplied separately to connect the socket to your wiring. The alarm
contacts have no voltage present, but we recommend that the wiring is connected by a suitably qualifi ed technician (electri-
cian or similar).
An alarm can be triggered by one of the following conditions:
• Loss of power.
• High temperature inside the refrigerator (1ºC above setpoint).
• Low temperature inside the refrigerator (1ºC below sepoint).
CONNECTION OF ALARMS
*Normally Closed
Will open loop upon alarm
situation (No 1) *This is the
optimum option as any break
in the loop is detected.
Normally Open
Will close loop upon alarm
situation (No 2)
Common
At least one wire is connected
to this pin (No 3)
All forced draught refrigerators such as this one requires constant air fl ow throughout the cabinet to maintain the desired
temperature. Correct loading of the shelves must be considered for effi
cient refrigeration performance.
• Never block off air vents in the rear panel if fi tted.
• Allow air space around the product on each shelf.
• Distribute the load evenly over all of the shelves rather than stacking everything on one shelf.
• Whenever possible the load should be chilled prior to loading to reduce the eff ect on the temperature inside
the refrigerator. If this is not possible then load the product a little at a time.
•
All TELR/TLR Refrigerators have loading requirements. When loading, product should be evenly distributed
throughout the refrigerator. It is important to leave 10% of each shelf level free (3cm front, side, rear and between
products) this allows air to fl ow evenly throughout the cabinet and maintain temperature accuracy in the refrigerators work-
space.

CALIBRATION
Calibration of the unit ensures correct product temperature and optimal refrigerator perfrormance. Calibration should be
done by a trained technician.

the following parameters will be available
Ot - Sensor Off set in Bottle
OE - Return Air Sensor Off set
O4 - Low Temp Alarm Sensor Off set
dP1 - Current Temperature of the Bottle Sensor
dP2 - Current Return Air Temp
Calibration is normally performed at 5°C. This procedure is a standard procedure used by Thermoline Scientifi c.
The aim when calibrating a Thermoline Laboratory Refrigerator is to have the Bottle at 5°c. This is acheived by placing a refer-
ence sensor in the bottle or in a bottle adjacent to the units bottle and noting the indicated temperature. The OE parameter is
then adjusted to increase or decrease the air temperature until the reference sensor reads 5°c.
Once the reference sensor has an average temperature of 5°c adjustments to Ot are made so that dP1 (Display Temperature)
equals 5°c.
