4.3 LCD window
unistat control V3.8.1
A numerical is not sufficient for this sophisticated unit. The illuminated LCD window contains
the alpha/numeric display in two rows with 16 digits each row (picture 1 see drawing at the
last page).
4.4 Flow Diagram
The flow diagram is situated in the top third of the control panel (picture 1 see drawing at the
last page). It is the status display path of the thermostat liquid. The four green dots at the
start, before and after the pump (LED 3,4,5,6 see drawing at the last page) are illuminated, if
the pump is turned on. The yellow dot (Led 7), when the heater is turned on and the green
dot bottom right (LED 8), when the cooling is on. Additionally the green dot (LED 10) shows
the power is on to the compressor, above the green dot (LED 9) is for an activated HT chiller
(if present). One of the two red dots, connected by a dotted line shows if internally (jacket
thermoregulation, LED 2) or externally (controller / reactor thermoregulation, LED 1 in reactor
symbol) controlled.
4.5 Signal Generator
The signal generator provides information of events that occur suddenly or due to a faulty
operation. Characteristic sounds are for certain events. The signal is not loud enough to be
used as a warning signal. The POKO (program 8) together with suitable externally acoustic
device should be used for that purpose.
4.6 Remote Control
The control panel can, following the steps of ‘removal of control panel’ be removed from the
unistat control and used via a cable connection. If the electric connection is interrupted, the
unistat control will stop thermoregulation and an emergency shut down will result.
Please switch off the thermostat in this case.
5. Switch on
After switching on the main switch, the control panel and the controller carry out an
extensive self-diagnosis. A message will be displayed if anything unusual occurs.
The important status information will be displayed as message. The following message could,
for example, appear:
The controller has been programmed for automatic switching on after the restoration of
power, after failure of the main power supply.
Automode: ein
or
Automode: on
5
or
Automode: active
Attention: one of these messages will appear depending on the language chosen (set with
program 90).
If you activate a function via the ‘external control signal’ (program 28), the following
message will be displayed:
Zweiter Sollwert
or
Second Set point
or
Consign 2
