If the device is in remote control mode then the variable (capacity) with which
the cooling unit or heater is controlled can be set using interface commands.
This section describes how the actuating variable can be set.
The device is switched on.
1. Bring up the <Main menu>.
2. From the <Connect unit> submenu, select the menu option <Actuating
variable>.
3. Select Digital or EPROG in the dialog window.
Digital can only be selected if remote control mode is activated.
EPROG can only be selected if the electronic slide-in module with analogue
connections is available and the capacity has been defined as an input
variable for EPROG in the submenu <Analogue module>. The remote
control mode must be deactivated.
The actuating variable is set.
The current device status can be queried via an interface command.
The device is connected to a PC via an interface.
1. Enter the command "status" in the terminal program and press [Enter].
The device responds with a status message. If an alarm or warning is
pending, the device sends the respective alarm or warning message to the
status query. Explanations of the status messages as well as alarm and
warning messages can be found in the Appendix.
Working with the programmer
Temperature control profiles are defined temperature profiles with a setpoint
temperature as well as a predefined temperature control duration or a
predefined gradient.
The programmer calculates a temperature ramp from these programmed values.
Use the profile timer function to start individual temperature control profiles and
define the number of repetitions. Several temperature control profiles can be
combined into one profile series.
In order for programmed temperature control profiles to run automatically, the
device must remain switched on.
