5.1
Installation
Setup
The 2100 controller is a precision instrument which should be located in an appropriate environment. The location should be free from excessive dirt, moisture, vibration, or temperature variations. There should be no present danger of
spilled liquids.
5.2
Heater/Stirrer
Connect the heater to the back of the controller into the socket labeled
“HEATER”. Be sure the heater cable is adequate for the amount of current required and that the heater is wired correctly and safely. See Figure 10 on page
56 for heater wiring. If applicable, connect the stirring device to the back of the
controller in the socket labeled “STIRRER”. BE SURE THAT THE COMBINED CURRENT OF THE HEATER AND STIRRER DOES NOT EXCEED 10 AMPS.
5.3
Control Probe
Connect the control probe into the socket at the back of the controller labeled
“PROBE” (see Figure 8 on page 56). 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 rating of the probe and be careful it is not exceeded.
Normally the 2100 controller is set up to use a 100Ω platinum probe. If better
resolution and stability are desired the 2100 may alternately be configured to
use Hart’s 2611 linearized thermistor probe. The controller operating temperature range with the thermistor probe is –10°C to 110°C. For information on
setup for the thermistor probe see Section13.
5.4
Thermocouple
Connect the optional thermocouple cut-out probe to the back of the controller
to the connector labeled “TC”. Insert the probe into the bath or system being
controlled. If the safety cut-out feature is not to be used then this input must be
shorted with a small wire jumper in order for the controller to operate properly
(see Figure 9 on page 56).
5.5
Power
Connect the controller power cord to a power source of the appropriate voltage
and current rating. This can be 115/230 VAC (±10%), 50/60 Hz. Check to see
