Badger Meter SRD/SRI Valve Positioners - Manual (Page 54)

DECOMMISSIONING
Before decommissioning the unit, disconnect the supply air
and the electrical input signal
After disconnecting the electrical input signal the last
confirmed configuration of the positioner is preserved in
the memory
Exchange of Device
If a temporary decommissioning of the SRD and a later
mounting to another actuator has to be carried out, before
disconnecting, we recommend to Reset Configuration in
Menu 9 1 So the default settings ”Ex-Factory” are reactivated
This facilitates a later recommissioning
MAINTENANCE
The SRD960 requires no periodical maintenance
When replacing components during repair work,
“Safety Requirements” on page 66 must be observed!
Service Plug and IrCom
All basic instruments of the SRD960 are equipped with
a service plug A There via RS232 a PC with PC20 / PC50
(FDT-Software) can be connected via modem EDC82 (galv
separated, not Ex)
This universal interface, together with the PC software,
allows the configuration of all SRD versions independent of
the protocol—thus versions HART, FOUNDATION Fieldbus,
PROFIBUS PA, FoxCom and also the version “without
communication” can be configured from the PC, without
having to acquire expensive modems For details see TI
to EDC82
The service plug (6 pole pin strip) is accessible from the side
after unscrewing of cover to electronic compartment The
6-pole connector links EDC82 modem with SRD, and from
EDC82 a 9 pole subD cable links to RS232 interface of PC
Figure 39: Service plug and IrCom
If the SRD is equipped with option IrCom B , communication
can take place without contact via infrared with the
positioner (even with closed cover) Modem IR Interface (not
Ex) is connected via RS232 to a PC (for practical reasons a
notebook) with software PC20 / PC50 and makes possible a
range of approximately 1 meter
(If the notebook has an IrDa interface, this cannot be used,
despite similar technique The IrDa instruction set has no
communication instructions for positioners )
Supply Filter Replacement
An obstructed supply filter can be replaced Unscrew the air
supply fitting, remove the filter and exchange the filter with
a new one
Pneumatic Amplifier
Upon unscrewing of lateral cover, the pneumatic
compartment is accessible
Figure 40: Single-acting amplifier
• Pre-Amplifier: Unscrew 4 screws K
• Amplifier: Unscrew 2 screws J
• When remounting, verify the correct seating of sealings
Damping Screws (Service Only)
The damping screws are adjusted optimal ex-factory; the
screw head is even with the amplifier surface Generally this
is the most favorable setting, without damping
