Press the ENT key to move the cursor to the offset data field. Use the Up or Down Arrow key to increase
or decrease the number. When the correct value is displayed press the ENT key to enter the offset, the
cursor will move to the upper left hand corner of the screen. Press the Up or Down Arrow key to scroll to
the next set parameter screen or press the ESC key to return to the System Status screen.
OFFSET: Allows calibration for the CO2 Sensor.
ACTUAL: Displays the current sensor reading.
QUALITY CONTROL
The following is a recommended procedure for quality control of this cabinet. If other regulations require
control in excess of this procedure, the more stringent guidelines should apply.
ACTUAL TEMPERATURE
The display temperatures should be validated on start-up and periodically thereafter to assure that the unit
is performing to the requirements. Validation can be accomplished by utilizing a NBS (National Bureau of
Standards) traceable thermometer.
The air temperature can be validated by placing the thermometer on a shelf or drawer so the thermometer is
not in direct contact with any metal surfaces. The displayed Air Temperature should read within ±2°C of
the NBS Thermometer. If the displayed Air Temperature is out of range enter an offset in the Air
Temperature Calibration screen.
Next place the NBS Thermometer in a vial of glycerol or another liquid that will simulate blood. Allow the
liquid and thermometer temperature to equalize before comparing the displayed product temperatures and
thermometer reading. The displayed Air Temperature should read within ±1°C of the NBS Thermometer.
If the displayed Air Temperature is out of range enter an offset in the Air Temperature Calibration screen.
Compare the temperature the NBS with the Chart Recorder temperature. It should agree within ±1°C of the
NBS Thermometer. If the Chart Recorder Temperature is out of range refer to the Chart Recorder Manual
to make adjustments.
ALARM TEST
Note: If the password protection is used the following screen will be displayed before allowing access
to the ALARM TEST screen. On initial start up there is no password protection the
passwords are set in the PARAMETERS group. If no password protection is used the
“ENTER PASSWORD” screen will not be displayed.

Press the ENT key to move the cursor to the four-digit password. Use the Up or Down Arrow key to
increase or decrease the number. When the correct password is displayed press the ENT key to enter the
password. If the correct password was entered the corresponding screen will be displayed. If a wrong
password was entered “WRONG PASSWORD” will be displayed on the bottom line. The password can
be re-entered or press the ESC key to return to the System Status screen.
ALARM TEST
The Alarm Test feature of this controller will test the High and Low Temperature Alarms for the two
product temperature sensors.
P1 LO TEMP TEST: Upper product sensor low temperature alarm test.
P1 HI TEMP TEST: Upper product sensor high temperature alarm test.
P2 LO TEMP TEST: Lower product sensor low temperature alarm test.
P2 HI TEMP TEST: Lower product sensor high temperature alarm test.
When the test is active the temperature will begin to rise for the high temperature alarm tests and fall for
the low temperature alarm tests. The temperature will continue to rise or fall for three (3) minutes then the
test will be stopped. When the temperature reaches the Alarm Set Point for the selected sensor the alarm
will sound and the display will show the alarm. The Alarm History Screen will log the temperature, time
and date that the alarm occurred.
Press the ENT key to move the cursor to the NO TEST SELECTED data field. Use the Up or Down
Arrow key to scroll through the tests. When the correct test is displayed press the ENT key to start the test.
Press the ESC key to return to the System Status screen.
This screen will be displayed when a test is active. To end a test press the ENT key to move the cursor to
the TEST data field and use the Up or Down Arrow key to scroll through the tests until “NO TEST
SELECTED” is displayed. Press the ENT key to end the test.

ALARMS
During normal operation, should an alarm occur, the ALARM button will glow red and an audible buzzer
will sound to indicate the presence of the alarm. Pressing the ALARM button once will silence the buzzer
for the period of time set for the RING BACK. If the alarm is still active after the RING BACK time has
expired the buzzer will sound again. Pressing it again will bring up the first alarm screen. Successive
presses of the ALARM button will bring up each alarm screen in sequence until the final screen indicating
“NO MORE ALARMS”. Pressing the ALARM button on the final screen then returns you to the screen
that was being displayed when the alarm sounded. Most alarms are self-explanatory.
During normal operation, when no alarms are active, pressing the ALARM button will display the
following screen:
The ALARM HISTORY screen will display the last alarm that has occurred. The controller will store the
last 100 alarms that have occurred. To view the Alarm History Log press the ENT button to move the
cursor to the alarm #. Using the UP and Down Arrow buttons scroll through the stored alarms.
Each alarm will display the date and time of the alarm along with the upper and lower product temperatures
when the alarm occurred.
P1: Upper Product Temperature.
P2: Lower Product Temperature.

Digital Outputs
Type relay
They are grouped in 3 with two common pole terminals in order to assemble the common poles easily. Be
careful to the current flowing in common terminals, because it must not exceed the rated current of each
single terminal, that is: 8A resistive for removable-screw terminals and 6A resistive for removable pitch
header terminals. The relays are divided into groups, according to the insulating distance. Inside each group
the relays have their single own insulation, so they must be exposed to the same voltage (in general 24Vac
or 230Vac). Among the groups there is double-insulation, therefore the groups can be of different voltage.
Anyway the double-insulation does exist toward the rest of the controller and its presence is guaranteed
among digital output terminals.
