5.2 Electrical Installation / Start of Operation
The ABNOX Temperature Controllers AXTR have inlets and outlets, as listed in
Table 3
. Please refer to
Figure
1
for the numbering of the connections. Please refer to model AXTR-024VDC or AXTR-230VAC for the voltage
supply at the marked pins (L+ / L- resp. L1 / N).
Pins 10 and 8 were configured as analog inputs for a PT100 2-wire resistance thermometer. The alarm outlets
for insufficient or excess temperature errors are integrated as make contacts at the pins 4 and 5, resp. 6 and 7.
The solid-state relay SSR will be connected at the pins 13 and 14 of the logic output.
IMPORTANT
In order to also detect sensor errors and cable breaks at the alarm outputs, the make-contact
relays are permanently locked within the valid temperature range. If the preset temperature is
exceeded or fallen below, the contact will be interrupted (see also chapter 5.3.2 Limit Monito-
