HOW TO DISMANTLE THE IAMS 0002 / 0022 / 0020
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
IAMS0002 and IAMS0022 are designed as SIL 2 devices with a high safety level.
Therefore, a continuous measurement of the outgoing current is carried out on
a 4...20 mA and 20...4 mA output signal. If the current output signal is different
from the internal calculated output value or the current output is 0 (due to e.g.
an open circuit breakage), an error mode switches on the red front LED.
This function is not a default option but must be actively selected via the
programming menu (S4-20 & S20-4).
The error mode can only be reset by switching off and then switching on the
supply voltage to the device.
