The optional AS-Interface module allows integrating the digital positioner DSR 500 in an AS-I
circuit and thus bypassing analogue output modules. This saves time in cabling and
maintenance.
If the AS-I module is to be retrofitted to an existing installation the kit contains the AS-I plug-in
plate, 1 connecting cable for M12-connections and a screw cap containing the common AS-I
LED's for visualisation.
Mounting the AS-I-module:
1.
Open casing cover.
2.
Connect positioner to Software DevConfig (plug 7).
3.
Change set point source to „digital" (can be found at positioner setting in tab
"Special").
4.
Store data to positioner.
5.
Cut positioner from 24 V DC supply.
6.
Plug AS-I module to prepared plug connection on connecting plate (8).
7.
Remove PG-gland on casing and screw in AS-I connection plug.
8.
Mount LED with socket to second screw joint.
9.
Connect AS-I and LED cables to AS-I module (plugs vary in pole number and cannot
be connected in the wrong way).
10. Close casing cover.
11. Connect positioner to AS-I circuit.
The AS-I module is supplied with AS-I address 0 as a standard. So the device can be fitted to
existing installations without problems.
