The device stays alive even at 3.7 mA input signal and com-
municates via HART. 4 mA is a normal state of the device.
When input signal is 6 mA and above, PST is possible. When
input signal is 8 mA and above, PST and travel calibration
are possible. The valve cannot be driven from the normal
position by any input signal. Thus the safety action needs to
be done with an additional solenoid valve.

System architecture
VG9000H can be connected directly to safety system
analog output module (AO, 4-20 mA). See Fig. 2 for the gen-
eral wiring principle.
VG9000H can also be connected to safety system digital
output module (DO, 0/24 V DC) via RCI unit. See Fig. 3 for
the wiring principle with RCI unit.
There is also a Local Control Panel option (LCP9H_). It can
be used together with VG9000H or VG9000H with RCI unit.
See Fig. 4. for the wiring principles with Local Control Panel.
See Section 3.5 for wiring details. See LCP manual
(7LCP9H70en) for further LCP details. See RCI bulletin
(9RCI21en) for further RCI details.
VG9000H_P must be used together with an additional sole-
noid valve (SOV). See Fig. 5 for the general wiring principle.

Markings
The ValvGuard is equipped with an identification plate
(Fig. 6).
Identification plate markings include:
Type designation of the ValvGuard
Enclosure class
Revision number
Input signal (voltage range)
Input resistance
Maximum supply voltage
Supply pressure range
Operational temperature
CE mark
Manufacturing serial number TTYYWWNNNN*)
*) Manufacturing serial number explained:
TT = device and factory sign
YY = year of manufacturing
WW = week of manufacturing
NNNN = consecutive number
Example: PH13011234 = controller, year 2013, week 1,
consecutive number 1234.
