Design and principle of operation
Type 3730-5 Positioner: the technical data for the explosion-protected devices may be restricted by the limits
specified in the test certificates.
Perm. ambient temperature
–20 to +80 °C for all versions
–45 to +80 °C with metal cable gland
–25 to +80 °C with inductive limit switch (SJ2-S1N) and metal cable gland
The temperature limits for the explosion-protected devices may be further re-
stricted by the limits specified in the test certificates.
Influ-
ences
Temperature ≤0.15 %/10 K
Supply air None
Effect of vibration ≤0.25 % up to 2000 Hz and 4 g according to IEC 770

Explosion protection
See Summary of explosion protection approvals
Electrical connections
One M20 x 1.5 cable gland for 6 to 12 mm clamping range · Second M20 x
1.5 threaded connection additionally exists · Screw terminals for 0.2 to
2.5 mm² wire cross-sections
Degree of protection IP 66/NEMA 4X
Use in safety-instrumented systems
(SIL)
Emergency venting at 0 V or over
the optional solenoid valve
Observing the requirements of IEC 61508, the systematic capability of the pi-
lot valve for emergency venting as a component in safety-instrumented systems
is given.
Use is possible on observing the requirements of IEC 61511 and the required
hardware fault tolerance in safety-instrumented systems up to SIL 2 (single de-
vice/HFT = 0) and SIL 3 (redundant configuration/HFT = 1).
