With 4 To 20 Ma/Hart; Electrical Data - Siemens SIPART PS2 Operating Instructions Manual

Technical data
7.2 With 4 to 20 mA/HART
Note
The following applies for exhaust air outlet with sound absorber
The positioner is supplied as standard with a sound absorber. To provide an outlet for the exhaust
air, replace the sound absorber by a G¼ pipe coupling.
The following applies for enclosure ventilation
1. With the "flameproof enclosure" device version in an aluminum enclosure with order suffix
-Z K50 "Operation with natural gas", you can completely collect and discharge the escaping
natural gas.
2. In all other device versions, the escaping natural gas is released into the environment.
Maximum values for escaping natural gas
• The quantity of escaping natural gas is negligible during regulated operation.
• If a control error occurs, a maximum of 30 Nl/min of natural gas will escape at the enclosure
vent
