HOW TO DISMANTLE SYSTEM 4000

First, remember to demount the connectors with hazardous voltages.

Picture 1:

Detach the device from the DIN rail

by lifting the bottom lock.

When front LED lights red / display shows AO.ER

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.
