The device can switch actuators, such as solid state relays or power contactors, via the outputs. Depend-
ing on the ordered variant, the device has one of the following output configurations:

Micro USB connection
The device has a type B micro USB socket, which functions as a setup interface. This socket can be
used to establish a connection to a PC or Notebook on which the setup program has been installed. The
setup program can be used to configure the device, for which there is an extensive range of configuration
options.
NOTE!
The setup interface (USB) is not intended to be used for a permanent connection.
Always disconnect the USB cable from the device as soon as you have finished working with the setup
program.
The length of the USB cable should not exceed 5 m.
It is not possible to establish the connection via a USB hub.
2.7
Timer
The device has a timer. The timer signal can be output via digital outputs or used for internal functional
links. A relative timer time can be configured. Following start of the timer via the keypad or a digital signal,
a signal is output for the timer runtime. Once the timer has ended, the device provides a timer end signal.
The timer start time can be delayed by setting a lead time. The timer end signal can also be set as infinite.
With this setting, the timer must be acknowledged in order to be ended.
The timer start time can be delayed through a tolerance band around the setpoint value. Monitoring of
the tolerance band during the timer runtime can be configured.
The timer signal to be output can be inverted.
NOTE!
The digital signals are inactive after power ON. No timer values are saved beyond power failure.
2.8
Temperature display
The temperature unit can be set to °C, °F or "none" via a global parameter. Internally, the device always
works in °C. After being changed to °F, the device converts all of the values for operation, display, and
the interfaces.
NOTE!
The device converts the entire configuration, such that even a configuration set up in °C works that same
when changed to °F.
