Siemens Superheat Controller CE1N3372en_02
Smart Infrastrucutre 2022-02-16
To operate the controller, use the operating buttons on the controller front. The
operating buttons provide the following functions:
• Use the <OK> button to enable changes or confirm a change.
• Use the +/- buttons to change flashing data, or select the information screen.
• Press the <ESC> to exit out of the current level and back to the previous
one.
• By simultaneously pressing the buttons +, -, <ESC> and <OK> for more than 5
seconds the controller gets reset to default settings.
A flashing display indicates adjustable data.
Reset function may only be carried out with the machine at a standstill.
Operation
For the configuration and fine tuning of the superheat controller, there are different
operating levels and operating modes available.
In normal operation, PolyCool™ is in the regulation mode. Follow procedures
below to access the operation mode, as appropriate.
Operating modes
Procedures
In regulation mode, simultaneously press down the + and - buttons for at least five seconds. Press
<OK> to confirm when C1 is flashing.
Configuration mode *
Select the mode with +/-, and press <OK> to proceed. Or, press <ESC>
to exit out of the current operation level.
Parameter mode
Simulation mode **
* The circuit can only be enabled or disabled in the configuration mode.
** The simulation mode (SIMU) is only applicable to Circuit 1.
If the controller has already been configured, the regulation mode will automati-
cally be activated when switching on. From any other mode, the controller will au-
tomatically return to the Regulation mode after 15 minutes.
Before accessing the specific operation mode, users are required to specify the
circuit. By default, circuit 1 is selected and cannot be disabled.
If settings in the configuration mode are changed while the controller is in operation
(does not apply to units), controller output Y1 (Y2 for circuit 2) will switch to 0 V. In
that case, the control will be released again only after all following parameters have
been enabled by pressing the <ESC> button on the right (controller must be
brought into the Regulation mode).
Before configuring the controller, you need first specify and enable (if needed) the
circuit, C1 or C2, as appropriate. By default, C1 is the working system and cannot
be disabled.
After selecting the circuit, go to the configuration mode (CONF) and select the
<ENABLE> → <COMP> parameter. Set the parameter value as ON or OFF by
pressing +/-.
