— FM/CSA: (IS) Class I, Div. 1, Groups ABCD, T6/
T5/T4
– NEC 505: Class I, Zone 2 Group IIC T6/
T5/T4.
– NEC 500: Class I, Div 2 Group IIC T6/T5/
T4.

• For explosion proof installations (i.e. (XP) Class I,
Div. 1), please contact factory for options.
With the HART ® option comprehensive sets of mainte-
nance and diagnostic data can be called up directly at
the positioner itself:
• zero point and range
• actuating speed
• original & current stats
— Actuator leakage
— Operating hours
— Min/max temperatures
— Valve limit position (i.e. change of stroke length
due to seat wear)
• dead band in both directions
• number of alarm reports
• number of directional changes
• total travel
In addition, you may call up data about the controlled ac-
tuator:
• instrument number
• type of actuator
• operating mode
• process data
• parameter data
With the SIPROM PS2 Software interface, the current
maintenance data can be remotely compared with previ-
ous information to quickly detect any deviations so that
corrective action can be taken. And, actuator and valve
problems can be caught early to allow ample time to
schedule repairs.
