Active if error
You can use this parameter to set whether the device is to activate the cool-
ing stage in the event of an error (fail-safe mode). The following types of er-
ror are recognized:
▪ The input signal for the temperature is in an impermissible range (e.g. ca-
ble break, sensor defective)
▪ The transformer load current is in an impermissible range
9.11.2 Set the operating mode
You can use this parameter to set the cooling system control operating
mode. You can select the following options:
▪ Automatic: The device starts and stops the individual cooling stages auto-
matically.
▪ Manual: You can start and stop the individual cooling stages via the visu-
alization [►Section 9.11.1, Page 153] or the control system.
To set the operating mode, proceed as follows:
1. Go to Settings > Parameters > Cooling system > Cooling system con-
trol > Operating mode.
2. Select the desired option.
3. Press the Accept button to save the modified parameter.
9.11.3 Deactivating cooling system control
Via a signal at the digital input I: Deactivate ISM cooling system control you
can deactivate the cooling system control, for example to control the cooling
stages via an external device. When configuring the digital input, refer to the
section Configuring digital inputs and outputs [►Section 9.30, Page 295].
9.11.4 Configuring load-dependent mode
In load-dependent mode all cooling stages are activated if the load current of
the transformer is greater than the set switching point. You can set the
switching point as a percentage in relation to the transformer rated current.
