MULTICAL® 803 & ULTRAFLOW®
5 Electrical connection
5.1 Connection of temperature sensors
Temperature sensors are connected to MULTICAL® 803 via the screw terminals on the connection
PCB. It is possible to use both 4-wire and 2-wire sensor types. When using 2-wire sensors, it is
important to mount the supplied jumper on the pins marked with 2-W, located directly above the
screw terminals on the connection PCB. If the supplied jumper is lost, it is possible to terminate
the extra connection terminals by short-circuiting them in pairs as illustrated in red in the table
below.
