9.3.3 Adding and replacing DIQ or MIQ output modules
Only replace any DIQ or MIQ output modules (all DIQ or MIQ modules with relay
contacts and/or electrical signal outputs) while the DIQ/S 28X system is
switched off. Defective DIQ or MIQ output modules are removed in the reverse
order to that of the installation. The installation is described in the I
NSTALLATION
chapter of the respective component operating manual.

Select the required inactive dataset with

and confirm with
<OK>
. The system changes to the measured value display. The
IQ sensor takes over all settings of the inactive dataset. As soon as the
IQ sensor is ready for operation, it delivers a measured value.
WARNING
There is also a danger to life from voltages that may pres-
ent a hazard of electric shock on the relay contacts of
open DIQ or MIQ output modules (e.g. DIQ/CR3 or MIQ/
CR3). Output modules with relays may only be opened if
all external voltages have previously been switched off.
Secure all external voltages against being switched on
again for the duration of the work.
When replacing DIQ or MIQ modules make sure that the substitute
module has at least the software status of the active module.
