Startup Operation
5.1
Preliminary checks prior to start-up
The following points must be checked before commissioning:
•
The supply power must be switched off.
•
The supply power must match information on the name plate.
•
The pin assignment must correspond to the connection diagram.
•
Sensor and transmitter must be grounded properly.
•
The temperature limits must be observed.
•
When the sensor (SE41F, SE21, SE21F) and transmitter (S4) are delivered as a pair, the
data memory module (external FRAM) is located in the sensor. The data module stores the
sensor data, e.g., size, Cs, Cz, type, etc., as well as the setup data on the transmitter after
commissioning.
•
Prior to commissioning, plug the external FRAM for the appropriate sensor (order no. is
printed on the FRAM and, if available, a TAG no.) to the connection board for the installed
transmitter. Then screw to the connection board (captive).

Important
If a transmitter is ordered for an older model sensor (see model number), an external FRAM is
already connected to the connection board. You will also find the information Cs = 100% and
Cz = 0%, which is required for sensors from older product lines. See also chapter 11
"Supplementary information: Operating S4 with an older model" in the operating instructions.
