TC-Kit (+)
5.1 Description of functions
The cooler is controlled by a microprocessor.
The programmable display shows the block temperature in
the selected display unit (°C / °F) (factory preset °C). Applica-
tion-specific settings can easily be configured guided by the
menu, using the 5 buttons. For one, this applies to the target
outlet dew point, which can be set from 2 to 20 °C (36 to 68 °F)
(factory setting 5 °C/41 °F).
And then the warning thresholds can be adjusted for low and
excess temperature. These are set relative to the outlet dew
point τ setting.
a
For the low temperature the range is τ
imum 1 °C cooling block temperature), for the excess temper-
ature the range is τ +1 to +7 K. The factory settings for both
a
values are 3 K.
The flashing display as well as a red LED on the display mod-
ule along with the status relay indicate the conditions are be-
low or above the configured warning range (e.g. after switch-
ing on).
The outputs are:
A potential-free status output. The relay is activated when the
block temperature is within the target range. The output also
serves as collective alarm for device faults, moisture ingress,
etc.
A switched output for connecting a gas pump. The output
uses the same relay as the status output. This output can only
be used for pumps designed for 24 VDC operating voltage.
Another relay output is available for switching up to two peri-
staltic pumps. The pumps are supplied with the mains voltage
and can be shut off via the device menu for maintenance pur-
poses.
The TC-Kit can optionally be configured for connecting a
heated line, which can be either self-regulating or a heated
line regulated by the cooler.
Operation via 115 VAC/230 VAC and using the regulator for a
heated line requires the optional expansion module.
