Operation
Controller positioning -
The TC-200D temperature controller is supplied
with a detachable temperature probe (Figure2).
This useful feature enables the TC-200D
temperature controller to be positioned away
from damaging fumes.
The temperature controller is factory set such that
the retort clamp is positioned for mounting on a
vertical retort rod. To mount the TC-200D
temperature controller on to a horizontal retort
rod, ease back the clamp situated at the rear of
the controller sufficiently to clear the right-angled
raised location. Rotate clockwise by 90° until the
clamp snaps back into the location.
Probe positioning -
For optimum temperature control, ensure the end
of the sensing probe is immersed at least 20mm
deep into the medium being controlled. The
temperature probe when not in use should be
placed in the probe holder located on the left
hand side of the TC-200D control panel. For
safety and to avoid contamination, always wipe
the probe clean prior to placing into holder.
Using the TC-200D temperature controller
The TC-200D can be used in two different
modes, either as a temperature controller
('control mode') or as a digital thermometer
('monitor mode').
To use the TC-200D in control mode
Ensure that the TC-200D temperature controller
is connected to the hotplate. Also ensure the
temperature probe is attached to the controller
and immersed in the medium to be controlled
before switching on at the mains.
HP-200-S, SHP-200-S, HP-200-C and
SHP-200-C
Turn the unit on using the On/Off switch at the
side of the unit. The TC-200D will power up in
monitor mode. To turn on the temperature
controller in control mode, turn the heat control
clockwise on the front panel of the hotplate.
SHP-200D-S and SHP-200D-C
Turn the unit on using the On/Off switch at the
side of the unit. The TC-200D will power up in
the last mode used. To change from monitor
mode to control mode, press either the '+' or '-'
key on the TC-200D. To turn on the temperature
4
controller in control mode, turn the heat control
clockwise on the front panel of the hotplate; the
LED display will show "---".
The TC-200D temperature controller in control
mode is indicated by the illuminated amber
contact thermometer indicator on the front panel
of the hotplate (Figure 3). The LED and display
will be visible on the TC-200D temperature
controller panel (Figure 5) and the current
temperature of the medium will be displayed.

NB: Turning the heat control clockwise on
the hotplate turns the TC-200D temperature
controller into control mode and cannot be
used to set the hotplate temperature.
To set the temperature in controller mode
Press the + or - key once to instigate the
temperature set point mode. This is indicated by
a flashing LED on the TC-200D temperature
controller display. To select the temperature, use
the '+' or ' –' keys to obtain the desired
temperature. To set the temperature, release the
key. The LED will cease flashing once the
temperature has been set. With the probe in the
sample, the thermometer LED will illuminate as
follows:
❖ Green – temperature set point not reached
❖ Amber – liquid at set point
❖ Red
– liquid hotter than set point
NB: To obtain accurate temperature control,
the minimum temperature set point must be
at least 15°C above the surrounding ambient
temperature.
