FAQ
Q: Can I use a separate DPDT relay for critical
actuation/deactuation points?
A: Yes, if actuation and/or deactuation at the same point is
critical, it can be achieved by using a separate DPDT relay. Ensure
it has a separate power supply for its coil.
Q: What do I do if I need non-standard options or
accessories?
A: Contact the sales office for non-standard options or
accessories. The manufacturer will provide details after agreement
of supply with the customer.

CAUTION : Supply pressure of air/inert gas = min. 2 and max. 7 bar
Note:
1. The minimum differential increases with the setpoint. The differential
values mentioned in the above table are approximate maximum for FSR. The
differential value will vary according to the pressure range selected and
microswitch type. For actual values of differential please contact sales
office.
If actuation and/or deactuation at same point is critical part of operation,
then it can be achieved by using a separate DPDT relay. This relay will need a
separate power supply for it’s coil.
