SA 5545 Reactor control unit Chapter 1 Introduction 1-1
1 INTRODUCTION
The SA 5545 reactor control unit is an instrument with a high accuracy in
temperature control, used for temperature control of one or two reactors.
With its wide temperature range it can be used in a large field of chemical
applications with different sizes of reactors with glass or metal coils.
1.1 Description of the instrument
The SA 5545 reactor control unit is used to regulate the temperature of the
reactor coil. The control unit covers the power supply and the electronic
control circuit. The housing is made of stainless steel. A switchable net
entry with on/off switch and two amphenol sockets to connect up to two
reactor coils, are situated at the back of the unit. Also two dummy switches
are present for switching when only one reactor is connected. The front
panel contains the controller part with temperature display and foil buttons
for channel and temperature selection.

1.2 Operating principle
The control unit is working according the P.I.D. principle. P.I.D. stands for:
proportional integrated differentiation principle.
The circuit operates by comparing the actual temperature in volts to a
preset value of volts. When the temperature in the reactor is almost
reaching the preset value, the heating element increases step by step the
temperature to avoid overshoot.
The actual temperature of one channel is displayed. The LED number of
the displayed channel is on. The preset temperature of a channel can be
read by keeping pressed the corresponding ‘S’ button. The preset
temperature can be adjusted by the up and down arrow buttons.

1.3 Safety precautions
Only qualified persons should carry out all adjustments, maintenance and
repair of the instrument.
1. The instrument is designed for laboratory use.
2. Before the instrument is connected to the mains and switched on,
check whether the required voltage (indicated on the net entry at the
back of the instrument) corresponds with the line voltage.
3. The instrument power cord must only be plugged into a line supply
outlet with ground protector (earth). If an extension cord is used, make
sure that the protector line is not interrupted.
4. Opening of the instrument or disassembling parts of the instrument
while connected to the main power supply can cause severe electrical
damage along with physical injury. Before any service, repair or
change of parts, the instrument has to be disconnected from all power
supplies. Service and repair work on the voltage carrying instruments
should be avoided whenever possible. If such work is absolutely
necessary qualified personnel, who are aware of the hazards, should
carry it out.
5. Whenever it is likely that safe operation is impaired, the instrument
must be made inoperative and secured against unintended operation.
The appropriate servicing personnel must then be informed.
6. Never place the unit in an area where it will be exposed to extreme
heat, moisture or corrosive materials.
7. The instrument must be disconnected from all electrical sources when
a fuse is to be renewed.
Skalar Analytical B.V. does not accept liability for any consequences
caused by irresponsible use or irresponsible handling of the instrument, nor
for the effects and consequences induced by its use.

2 UNPACKING AND INSTALLATION
2.1 Unpacking instructions
While unpacking do not discard any packing materials, till all parts have
been unpacked and checked against the packing list to insure all items are
accounted for. If any item is missing first check the packing. If it still cannot
be found, make a note of it giving as clear a description as possible using
part numbers from the manual and immediately inform the forwarder and
the supplier (see delivery conditions). Even when you think that all items
have been accounted for, check the packing.
Should there be any damaged or broken parts, repack it in the original
packing, and immediately inform the forwarder and the supplier who will
give further instructions. If the goods are supplied on trial, the original
packing material must be used for return shipment unless better is
available.
2.2 Location
The control unit should only be placed on a level, clean, dry and sturdy
surface. Place the control unit near the analyzer on the table or on a shelf
above the analyzer.
Do not locate the unit:
• In direct sunlight.
• Near an air conditioning unit.
• Near any heat or cooling source.
• Near equipment that generates intensive magnetic or electric fields.
• Near equipment that generates high frequency.
2.3 Electrical requirements
Power supply; before connecting, check the power supply is set correct for
the instrument (220-240 Volt/50 Hz or 110-120 Volt/60 Hz), see net entry at
the back of the instrument.
Note: If the power supply is not correct, open the fuse department with a
small screw driver to set the fuse holder to the required voltage and to
replace the fuses to the required voltage (2x 1.6 A for 230 V, 2x 3.15
A for 115 V). Make sure to place the fuses at the same place in
the fuse holder.
The instrument must only be connected to a line supply with ground
protector (earth). If an extension lead is used make sure the ground
protector line is not interrupted.
Max. power consumption is 320 VA, when two reactors are connected.
When one reactor is connected, the max. power consumption is 160 VA.

3.3 Switching off one reactor
To switch off one reactor:
Press the button of the reactor to be switched off (S1 or S2) and the
Standby button at the same time during 2 seconds. The display of that
channel will show OFF.
3.4 Disconnecting one reactor
When a reactor is disconnected from the control unit, the corresponding
dummy switch at the rear must be set to ‘OFF’. If the dummy switch is not
put in the correct position the controller will give an audible signal (which
can be switched off by pressing the ‘down arrow’ button) and the display
will show ‘F1’ or ‘F2’ (depending on which channel the error occurs).
3.5 System controller
If the control unit is connected to a system controller:
The reactor can be switched on/off by means of the system controller (see
the FlowAccessTM manual). However, when one reactor was switched off
before an analysis and the system was switched off after the analysis by
the system controller, when the system is woken up the control unit starts
with both channels switched on.
