To monitor the temperature of an external hydraulic circuit, an external temperature sensor can be connected to the unit (→ Installation).

Prerequisite:

  • ZE additional equipment

input source

The parameter defines which source is used to transmit the actual temperature value from the external sensor.

locally

The actual temperature value from the external sensor is transmitted directly via the connection to the unit. To do this, connect the external sensor to the unit. The sensor type can be set manual using the [External Sensor type] Parameter.

OPcUA

The actual temperature value from the external sensor is transmitted via the OPC UA interface (higher-level system). To do this, The unit must be connected to the higher-level system via OPC UA. The connection for the external sensor (additional ZE equipment) is not required.

Sensor type

NOTE!

All sensor types must be adjusted manual.

  1. Select [Setting] > [External sensor] > [External Sensor type].

  2. Set the parameter to the desired type.

Switching external sensor

The parameter defines how the Controller behaves when an external sensor is connected.

  1. Select [Setting] > [External sensor] > [Switch Over Exernal Sensor]
  2. Set the parameter to the desired value.
automatically

The Controller on the external sensor is carried out automatically when it is detected.

NOTE!

If the sensor failure in the external sensor, the Controller is automatically switched to the internal measurement point. There is no adjustment of the temperature setpoint.

manual

The Controller on the external sensor must be switched on and off manual using The [external Sensor] function.

NOTE!

If the sensor failure in the external sensor, a warning message is sent and the Controller is automatically switched to the internal measurement point. The temperature set value is automatically adjusted with the actual value of the internal measurement point.

Manually switch the Controller on and switch off external sensor

NOTE!

It is only necessary to manually switch the external sensor Controller on and off if the [switch over exernal sensor] parameter is Set to “manual”. The [External Sensor] function is only available when the setting is “manual”.

  1. Select [Functions] > [External Sensor]

  2. Use the slider (, ) to switch the function on or off.
