HOW TO DISMANTLE SYSTEM 4000
First, remember to demount the connectors with hazardous voltages.

PR 4116 is designed as a SIL 2 device with a high safety level. Therefore, a
continuous measurement of the outgoing current is carried out on a 4...20
mA output signal. If the current is 0, an error mode switches on the red front
LED and disables the relays. This function is not a default option but must be
actively selected in the menu. The error mode can only be reset by switching
off and then switching on the supply voltage to the device.
