The internal temperature of the converter box and sensor heads should always

be within the ambient temperature range specifications. See

Specifications".

Limit Switch

Your converter box is equipped with a relay contact controlled by the measuring

signal. The switch point of this relay is adjustable within the temperature

measurement range. With this function, you can select to have the contact open or

closed when the measured temperature is either above or below a set temperature.

You can adjust the limit switch settings using the SP1 and SP1/TEMP values for

converter boxes with a display, or via the t1, ss, sx, and s1 UPP commands.

With this function, you can adjust the switch point of the relay contact to open and

close only when the measure temperature is above or below (depending on the limit

switch setting) a value that consists of the SP1/TEMP and the adjusted hysteresis.

You can adjust the hysteresis setting using the SP1/HYST value for converters with a

built-in display, or via the hl UPP command.

All sensor heads can be interchanged with any other sensor head without restriction.

When more than one sensor cable is connected to the converter box, any combination

of the available sensor heads is possible.

TO REPLACE THE SENSOR HEAD

1. Loosen the screw nuts and disconnect the M8 connector (male socket) of the

sensor head from the M8 connector (female socket) of the sensor cable.

2. With the new sensor head, align the pins and connect the M8 connector (male

socket) to the M8 connector (female socket) of the sensor cable.
