SW1-31 ECS1737-3 control module automation spare parts
Technical data of product parameters
The last item in the above list refers to a particularly progressive way of operating a safety valve. In this case, the SW1-31 ECS1737-3
valve is not held in the fail-safe end position (e.g. OPEN position) by excessive air or force but it is opened to approx. 98 %, for example. This increases reliability as the valve cannot get stuck in the end position and further SW1-31 ECS1737-3
diagnostic functions saved in the positioner can be performed.
Fig. 16 shows a connection employing the smart Type 3738-20 Electronic Limit Switch. Connection to the process
control system is established using the common wiring, which is a special benefit when upgrading older systems.
In this case, alarms are indicated by a NAMUR contact.If the test results are to be used, e.g. to achieve a longer test interval, performance of the partial stroke test must SW1-31 ECS1737-3
be documented. To do so, a setup as shown in Fig. 16 (schematic drawing in Fig. 17) can be used. The limit switch
of the Type 3730-x Positioner or the third travel contact of the Type 3738-20 Electronic Limit Switch are set to the
desired valve movement target. In the positioner, this can be done using the mechanical travel stop option, which
is a certified component. In the limit switch, the function of the NAMUR signal safely indicating the adjusted switching points has been certified by an independent expert body. The limit switch signal is recorded by the safety
PLC, time-tagged and archived
