1 Before You Start
1.1 Introduction
Fluke’s Hart Scientific Division’s 2200 Temperature Controller is a solid state
temperature controller. A unique combination of analog and digital electronic
circuitry provides exceptional accuracy and stability together with ease of oper-
ation and programmability.
Temperature sensing is done with a 2-wire 100 ohm platinum resistance probe
which plugs into the back of the controller. To maintain a constant temperature
the power to the heater is pulse width modulated by means of a solid-state re-
lay. The maximum current rating of the controller is 10 amps.
The 2200 controller can be easily programmed via the four-button front panel
or by the serial interface. Programming allows the user to set the control tem-
perature, units °C or °F, and the calibration variables. The process or actual
temperature is continuously displayed on an LED panel. The percent heating
power may also be monitored.
Before using the 2200 controller, you should understand the proper setup and
operation.

Before initial use, or after transport, or after storage in humid or semi-humid
environments, or anytime the dry-well has not been energized for more than 10
days, the instrument needs to be energized for a “dry-out” period of 2 hours be-
fore it can be assumed to meet all of the safety requirements of the
IEC-61010-1. If the product is wet or has been in a wet environment, take nec-
essary measures to remove moisture prior to applying power such as storage in
a low humidity temperature chamber operating at 50°C for 4 hours or more.
The instrument is intended for indoor use only.
The instrument is a precision instrument. Although it has been designed for op-
timum durability and trouble free operation, it must be handled with care.
Operate the instrument in room temperatures listed in Section 2.2, Environmen-
tal Conditions. The instrument is not vented. Therefore, clearance for ventila-
tion is not a requirement. However, do not place the instrument on top of a
calibration bath or dry-well where it would be in contact or direct path of heat.
DO NOT stack items on top of the instrument.
BURN HAZARD
The instrument can be used to control instruments which generate extreme tem-
peratures. Precautions must be taken to prevent personal injury or damage to
objects. Probes may be extremely hot or cold when removed from a calibration
bath. Cautiously handle probes to prevent personal injury. Carefully place
probes on a heat resistant surface or rack until they are at room temperature.
Fires and severe burns may result if personnel fail to observe safety
precautions.

Safety Information

ELECTRICAL HAZARD
These guidelines must be followed to ensure that the safety mechanisms in this
instrument will operate properly. The instrument must be plugged into an ap-
propriate outlet as specified in Section 2.1, Specifications, on page 9. Also, the
current and voltage capability of the instrument must not be exceeded. The
power cord of the instrument is equipped with a three-pronged grounding plug
for your protection against electrical shock hazards. It must be plugged directly
into a properly grounded three-prong receptacle. The receptacle must be in-
stalled in accordance with local codes and ordinances. Consult a qualified elec-
trician. DO NOT use an extension cord or adapter plug.
DO use a ground fault interrupt device. This system that is controlled by this
instrument may contain a fluid. A ground fault device is advised in case fluid is
present in the electrical system and could cause an electrical shock.
Always replace the power cord with an approved cord of the correct rating and
type. If you have questions, contact a Authorized Service Center (see Section
1.4).
High voltage is used in the operation of this equipment. Severe injury or death
may result if personnel fail to observe the safety precautions. Before working
inside the instrument, turn off the power and disconnect the power cord.
FLUIDS
Fluids used in the system controlled by this instrument may produce noxious or
toxic fumes under certain circumstances. Consult the fluid manufacturer’s
MSDS (Material Safety Data Sheet). Proper ventilation and safety precautions
must be observed.
The instrument is not equipped with cutout capability. User should use a
bi-metal cutout or other cutout device with the system, which will insure that
the flash point, boiling point, or other key fluid characteristics are not
exceeded.
1.3.2 CAUTIONS
To avoid possible damage to the instrument, follow these guidelines.
Do not plug the instrument into 230V if the indicator window of the power en-
try module reads 115V. This action will cause the fuses to blow and may dam-
age the instrument.
DO use a ground fault interrupt device.
Operate the instrument in room temperatures as listed in Section 2.2, Environ-
mental Conditions.
Calibration constants should only be changed by trained personnel. The correct
setting of these parameters is important to the safety and proper operation of
the instrument.
2200 Temperature Controller
User’s Guide

The Factory Reset Sequence should be performed only by authorized personnel
if no other action is successful in correcting a malfunction. You must have a
copy of the most recent Report of Test to restore the test parameters.
DO NOT operate this instrument in an excessively wet, oily, dusty, or dirty en-
vironment or place in locations where hot or cold liquids are splashed on it.
Most probes have handle temperature limits. Be sure that the probe handle tem-
perature limit is not exceeded in the air above the system controlled by this
instrument.
The instrument and any thermometer probes used with it are sensitive instru-
ments that can be easily damaged. Always handle these devices with care. Do
not allow them to be dropped, struck, stressed, or overheated.
DO NOT use this instrument in a system that exceeds the current capability of
the instrument as listed in Section 2.1, Specifications, on page 9.
DO NOT replace fuse(s) with one of a higher current rating or type. Always re-
place the fuse with one of the same rating, voltage, and type. The current rating
listed in Section 2.1, Specifications, on page 9 is the maximum for the instru-
ment. If the instrument is connected to a system which uses less than the maxi-
mum capability of this instrument, the fuses need to be changed in order to be
correct for the system. Once the instrument is connected to the system, the sys-
tem current needs to be measured or calculated and the appropriate fuse size
and characteristics selected. Section 4.5, Fuses, on page 15 can be used as a
guide for selecting a fuse.
Once the correct fuse type and rating is selected, the following information is
applicable. The instrument is equipped with operator accessible fuses. If a fuse
blows, it may be due to a power surge or failure of a component. Replace the
fuses once. If a fuse blows a second time, it is likely caused by failure of a
component. As a test disconnect the output device (heater) and apply power to
the rest of the system. Check to see if the fuse(s) blow. If the fuse(s) blow only
when the output device (heater) is connected, the fault may be in the heater. If
not, contact an Authorized Service Center (see Section 1.4).
If a mains supply power fluctuation occurs, immediately turn off the instru-
ment. Power bumps from brown-outs and black-outs can damage the system.
Wait until the power has stabilized before re-energizing the instrument.
For best accuracy, the instrument needs to be calibrated with the system it
controls.

4 Installation
4.1 Setup
The 2200 controller is a precision instrument which should be located in an ap-
propriate environment. The location should be free from excessive dirt, mois-
ture, vibration, or temperature variations. There should be no present danger of
spilled liquids.
4.2 Heater
CAUTION: Be sure that the current of the heater does not exceed the
maximum capability of the instrument (see Section 2.1 on page 9).
Connect the heater to the back of the controller using the socket labeled
“HEATER”. Be sure the heater cable is adequate for the amount of current re-
quired and that the heater is wired correctly and safely. See Figure 1 on page 13
for heater wiring.
4.3 Control Probe
Connect the control probe into the socket at the back of the controller labeled
“PROBE” (see Figure 2 on page 14). Insert the probe into the bath or system to
be controlled. For best stability and response time the control probe should be

located in close proximity to the heater. Observe the maximum temperature rat-
ing of the probe and be careful it is not exceeded.
Set the high limit (HL) less than or equal to the probe maximum temperature.
4.4 Power
CAUTION: Do not plug the instrument into 230V if the indicator window
of the power entry module reads 115V. This action will cause the fuses to
blow and may damage the instrument.
Plug the controller power cord into a mains outlet of the proper voltage, fre-
quency, and current capability (see Section 2.1, Specifications on page 9). In-
sure that the indicator window of the power entry module matches the voltage
of the mains supply.
Turn the controller on using the rear panel "POWER" switch. The controller
will turn on and begin to heat or cool the system to reach the previously pro-
grammed temperature set-point. The front panel LED display will indicate the
actual process temperature. See Section 4.5, Fuses for information on selecting
the correct fuse for the application.
When powered on the control panel display will briefly show a four digit num-
ber. This number indicates the number of times power has been applied to the
unit. Also briefly displayed is data which indicates the controller hardware con-
figuration. This data is used in some circumstances for diagnostic purposes.
