1 Preface
1.1 General guidelines
This installation manual describes the installation of the analog output of the SUFsg ultra low temperature -
freezer and is aimed at service personnel who should install it.
The repair of the cooling system must only be performed by personnel having specialized training and
special tools must be available.
References about the required qualification of the personnel can be found in chap. 2.1.
Before starting the service work at an SUFsg ultra low temperature freezer, compare order and serial -
number of the unit with the validity note on the front page of this manual.
The of electrical equipment marking of the components refers to the s. With other sizes of the circuit diagram
device the marking can deviate. Therefore use always the appropriated circuit diagram of the device.
Additional options are indicated in the text.
This manual will be updated if necessary. Always use the latest version of the manual.
All information about initial operation, normal operation, cleaning, alarm and error messages can be found in
the relevant operating manual delivered with the SUFsg ultra low temperature freezer.-
Before connecting the unit, compare the data given on the type plate with the values of
your power supply network.

2.2 Safety and hazard instructions
DANGER
Electrical hazard during live maintenance and repair work
Deadly electric shock.
Before conducting most of the described work, turn off the chamber at the main power
switch and disconnect the power plug
Take all precautionary measures that a unit which is disconnected from the power supply
will not be inadvertently connected to the power supply.
If the unit must be live to perform special service tasks: Make sure that a second person
is present who is able to switch off the unit in case of emergency.
CAUTION
Danger of cutting by sharp edges of sheet metal parts.
Cutting injuries.
Wear protective gloves during mounting and dismantling inner chamber and housing
because sheet metal components may be sharp-edged.
NOTICE
Danger of damaging electronic components by handling malpractices and electrostatic
discharge.
Malfunctions and damage of the electronics.
Prior to work at electronic components, take appropriate protective measures against
electrostatic discharge. Wearing ESD shoes and a grounding bracelet have shown to be
useful.
Before opening the lock and controller housing, electrostatically discharge by touching a
grounded metallic object.
Prior to work at the electrical equipment check identity of the components with the aid of
the wiring diagram. The assembly of the electrical equipment may be different from the
description in this manual.
NEVER let mechanical components hang at electric cables. Electric cables are not
appropriate to hold bigger components and will be damaged if you do so

4 Functional test of the analog output
1. Connect the chamber to the power supply and turn it on.
2. A current signal proportional to the temperature must be given out at the analog output.
3. e Connect a current measuring device (setting: mA) to pin 1 and 2 of the analog output. The current valu
shown in the table is given out at the analog output in accordance with the current interior temperature.
4. The reading of both the temperature value and the current value must take place within 15
seconds.
