OPERATING INSTRUCTIONS FOR LABCOLD BENCHTOP
BS BLOOD BANK
POSITION
The blood bank should be stood on a firm level surface away from direct heat sources such
as steam pipes, autoclaves or ovens. It is better to avoid direct sunlight if possible.
POWER REQUIREMENTS
The power cable with moulded on plug supplied with this blood bank is coded as follows:
Brown
Blue
Green and Yellow
- Live
- Neutral
- Earth
It is rated for 220/240 volts 50Hz unless made to your special order for a different supply. It is
essential that the blood bank be earthed. The supply must be fused at 13 amps unless
otherwise indicated.
BEFORE START UP
If the blood bank has been tilted during its positioning it is important that it is left to stand for
12 hours before connecting the power. (This procedure allows compressor oil to return to the
sump and prolongs compressor life expectancy).
The recording thermometer will need the pen fitted. Access to the recorder is by key (there
are two sets of keys supplied, one for the recorder and one for the door). Open the recorder
door and lift the pen arm gently away from the chart, remove the pen tip cover. To fit a new
chart, unscrew the outer knurled ring and remove from the shaft, lay the chart over the
spindle and rotate so the pen arm will touch the right time and day. Then screw the ring on
the spindle down to secure the chart and clip chart under the tab on the face of the recorder.
Lower the pen arm to its set position above the chart and close the outer door.
For full details of the recorder see section: Operating Instructions for the Chart Recorder.
OPERATION
Connect to the power supply. The operating temperature and alarm thresholds are factory
set and should require no adjustment. The blood bank will pull down to operating
temperature, which can be confirmed by the indicating and recording thermometer. This
blood bank has been set up to the parameters shown on the enclosed certificate and should
not require further adjustment.

DOOR LOCK
Door Lock Panel
Some models may be fitted with a magnetic lock controlled by a 12 character keypad. The
code for the lock is “1111”, this is factory set. After the code is put in, you then have a one
second delay before opening the door. After fifteen seconds the keypad resets and the door
will lock when closed. If there is a power failure the door will be unlocked, it is therefore
recommended that the key lock be used in the case of a prolonged power failure.
KEY LOCK PROGRAMMING
To reprogram the door lock with your own number proceed as follows:
(1)
Enter master code 1234
(2)
Enter the * key, 3 long beeps will be heard and the Green LED will
flash, indicating that the keypad is in programming mode.

(8)
Press #… if the two entries are identical 2 long beeps will be heard and
the RED and YELLOW LED’s will go off, the GREEN LED will continue
to flash. If the values are mismatched then 2 short beeps will be heard
and the old values will be retained.
(9)
Press the * key then the # key to end the programming, 2 long beeps
will be heard and the LED’S will return on their original state.

BLOOD MONITOR ALARM SYSTEM
Blood Monitor Alarm Display
The alarm provides information on a number of vital parameters. The normal state will be
indicated by the words “NORMAL OPERATION”. All alarm conditions will be shown on the
display (for a list press TEST once).
To avoid nuisance alarms there is an automatic delay of 3 minutes in initiating the audible
alarm after the alarm display shows a fault.
The MUTE button will silence the alarm system for a fixed period of 15 minutes. If the alarm
condition continues, the display will still indicate the alarm. At the end of the cancel period, if
the alarm state continues, the audible warning will recommence. The MUTE button can then
be depressed again if required.
Volt free remote alarm contacts are provided at the rear (Max 30V 0.5A). The remote facility
has an additional 6 minutes delay built in to avoid false calls to the switchboard.
For full details of the Blood Monitor see section: Blood Bank Alarm Unit.
TEMPERATURE ADJUSTMENT – SINGLE SYSTEM
Temperature Display.
To raise or lower the operating temperature of the blood bank press ‘SET’ once, the display
will flash, then use the up or down arrow until the required value is shown.

INNER DRAWERS
DO NOT OPEN MORE THAN ONE DRAWER AT A TIME
If your blood bank is fitted with drawers, they can be removed by extending the drawer fully
on its runners and pressing the black levers (right hand side up and left hand side down).
The drawer can now be removed.
To replace the drawer simply slide back into position. To adjust the drawer dividers
backwards and forwards, grasp the two ends of the divider and walk the divider along the
rods using a rocking motion. The dividers can be removed by undoing the screws holding on
the face plate and removing the rods from the keyhole slots.
PLEASE ENSURE THE INTERNAL DOORS OR DRAWERS ARE FULLY CLOSED
BEFORE CLOSING THE OUTER DOOR.
DOORS
The blood bank is fitted with self-closing doors. This feature works up to a 90º angle; any
angle more than this and the doors will stay in an open position.

CHANGING THE PEN
Fitting the pen arm
Pen Arm
Pen Nib
Wait until the unit is within its calibrated operating temperature range. Remove the pen from
its packaging (remove the tip seal) and gently lifting the pen arm slide the pen to the end
taking care that the tip points toward the chart. Undue force should be avoided as the pen
arm is sprung to ensure optimum contact pressure with the chart.
DOOR OPENING
A single lock located at the bottom right hand corner closes the door. The key should be
aligned with the slot in the lock in order to open the door. The key can then be turned 90°
counter-clockwise.
CHANGING CHART
In order to change the chart the centre hub outer ring must be removed. Lift the pen to a
vertical position. Take hold of the centre hub outer ring and turn by rotating it counterclockwise, until it releases. The chart can then be slid off the instrument. Replace with a new
chart by sliding the chart under the retaining clips at the top and bottom of the instrument and
position over the centre hole. To replace the centre ring, re-align it with the spindle, and turn
clockwise until it has tightened (it should only be finger tight).
ALIGNING THE CHART WITH THE PEN
Loosen the centre ring and rotate the chart gently until the pen tip is coincident with the
current time and day, gently retighten the centre ring by rotating it clockwise until finger tight.
CALIBRATION
The chart recorder is pre-calibrated and should require no adjustment, however, the pen
position can be altered by holding the pen with finger and thumb near to the spindle and
gently turning the screw with the back of the key. This can be repeated until the pen nib
indicates the required temperature.

USER CARE AND MAINTENANCE
The following routine cleaning and maintenance should be carried out in order to ensure that
the refrigerator continues to function effectively when in use.
THERMOGRAPH AND ALARMS
The recording thermograph and alarm system should be tested at least once each week,
preferably after changing the temperature chart. The records of such testing should be kept
in a permanent log.
The chart of the recording thermograph should be changed when completed, dated, labelled
for proper identification of the refrigerator and signed by the person responsible for changing
the charts.
Note: These charts should be retained for at least 11 years.
! Important !
The recorder battery should be changed every 6 months or if the unit fails to rotate or tick.
DOOR SEALS
The door seals should be visually checked for cleanliness, deterioration and air leakage at
least once each week.
OBSERVATIONS
The following checks should be carried out daily:
(a) For any unusual noise or apparent vibration;
(b) For any evidence of build-up of condensed water on the internal surfaces
of the refrigerator;
(c) For any condensation of water on external surfaces;
(d) That the air circulating fan operates;
(e) It is recommended that the blood bank be checked for loose fixtures and
fittings.
CLEANING
All internal surfaces should be cleaned periodically using a mild (neutral) detergent solution.
The coils of the external heat exchanger should be cleaned at least once every 3 months to
remove build-up of dust. Whenever blood is spilt on the internal or external surface of the
refrigerator, the spill should be wiped immediately clean and the surface decontaminated
using a suitable disinfectant. After decontamination, the surface should be rinsed clean.
Where manual defrosting is necessary care should be taken not to use sharp instruments,
which may damage the lining.

BLOOD BANK ALARM UNIT
Description
The blood bank alarm unit uses a micro-controller, which is programmed to provide all the
necessary functions. The unit is fitted to a blood-bank temperature-controlled cabinet to
ensure that if the temperature does not stay within predetermined limits, alarms are
generated to attract attention. The basic function of the unit is to sense the temperature in
the blood bank by means of a thermistor probe and to generate visual, audible and remote
alarms if the temperature moves outside pre-set limits. In addition a door switch senses
when the door is open and generates an alarm. The state of the blood bank is displayed, the
messages being one or more of the following:
NORMAL OPERATION
DOOR OPEN
LOW TEMPERATURE
HIGH TEMPERATURE
MAINS FAILURE
CHECK BATTERY
When the unit is switched on, or if the ‘TEST’ button is pressed, the unit first of all performs a
self check during which the display shows the programme version number, followed by the
above messages in sequence, and then the local sounder is activated briefly. After these
tests are complete the unit starts monitoring for faults, and when there is a fault, the
appropriate message is repeatedly flashed on the display, and, after a delay, the local and
remote alarms operate. In the case of two or more faults being present at the same time e.g.
‘OPEN DOOR’ and ‘HIGH TEMPERATURE’, the error messages are repeatedly flashed on
the display alternately, each for about one second. When the continuous message
‘NORMAL OPERATIONS’ is displayed a flashing hyphen between the words confirms that
the alarm programme is running normally. The display is a green electro-luminescent, 16
characters x 1 line module.
10
Delays in Operation of Alarms
To avoid nuisance operation there is a delay of ≈3 minutes after a temperature or door fault
is detected before the audible alarm is activated, however the alphanumeric display
responds immediately. If an audible alarm is cancelled and a further fault occurs, the audible
alarm will resound after ≈3 minutes. In the case of ‘MAINS FAILURE’, the alphanumeric
display and the audible and remote alarms are activated immediately. All of the alarm
indications cease as soon as the fault condition returns to normal. The ‘CHECK BATTERY’
alarm is advisory and does not generate an audible or remote alarm.
Remote Alarms
To avoid nuisance alarms the closure of the contacts
has an additional delay of 6 minutes built in to allow
the operator to accept the alarm before the
switchboard is alerted. To test the remote
connections, either an alarm must be triggered, by
opening the door for instance and the alarm left
unmuted for 6 minutes, or switch off the unit at the
mains. The contacts will change state after a short
delay.
Settings
The alarm has the following fixed settings built in:
- Acceptance of an alarm from detection of an abnormal state = 3 minutes.
- Acceptance of a door alarm = 3 minutes.
- Cancel time recall =15 minutes.
- Temperature settings Low alarm = 2oC, High alarm = 8oC.
Mute Button
This silences the audible and remote alarms for ≈15 minutes but only operates if there is in
fact a fault present, so that casual pressing of the button when all is healthy will not prevent
correct response to a later fault condition.
N.B. Following a failure of the mains, the MUTE button silences the sounder, which remains
silent until the mains supply is restored. During a failure of the mains the remote alarm
cannot be cancelled.
Test Button
Pressing the TEST button will restart the unit, repeating the above tests and resetting timers
and alarms. If any faults are still present, the appropriate message appears and the audible
and remote alarms operate after the normal delay (≈3 minutes), (except in the case of mains
failure).
11
Watchdog Timer
The watchdog timer is a part of the processor, which monitors programme operation, and if
for any reason the programme should halt, the watchdog timer will restart the alarm unit
thereby providing continuous protection.
Brownout Protection Circuit
The brownout circuit is included to protect against drops in mains supply voltage, which
might otherwise cause the alarm to malfunction. When the supply voltage falls below a
critical level and then returns to normal, this circuit restarts the alarm unit.
Standby Battery
The rechargeable battery is trickle charged when the mains supply is present, its condition is
monitored and if a fault is detected the ‘CHECK BATTERY’ message will be displayed. In
the event of a mains failure the battery will maintain the operation of the unit for ≈2.5 hours.
If the mains supply fails, the sounder pulses (≈2 per sec, ≈0.1 sec duration) until it is
cancelled, and it remains cancelled until the mains supply is restored. The alphanumeric
display read ‘MAINS FAILURE’ until the mains supply is restored or the battery is
discharged. The remote alarm activates and cannot be cancelled manually but resets when
the mains supply is restored. The remote alarm will remain activated even if the standby
battery discharges and the alarm unit shuts down.
! IMPORTANT !
When replacing the battery pack only use the recommended spare part of the correct type.
RoHS regulations have required the change from Nicad batteries to NiMH batteries, which
are environmentally friendly. The two different types are not compatible and if the incorrect
battery pack is fitted may damage the alarm system.
Electrical Interference
Although the alarm unit is tested to comply with the EMC Directive EN50082-1 for Immunity
to Electrical Interference, it is not totally immune to high voltage surges and RF fields. If such
high levels occur the unit has been designed to emulate mains failure by alarming locally and
closing the remote contacts.
Disconnection of the mains supply, the battery backup, and the restarting of the alarm will
normally clear the problem allowing the alarm to function normally.
