6.3.13 Input / Output Testing Functions
Input/output testing is used to ensure that the
connected components are in working order.
Relay Output Testing
Selection of a setting from relay testing closes the
corresponding relay and therefore switches on the
connected component. This makes it possible to
check that the relays are in working order and that
the wiring has been performed correctly.
Line no. Programming line
7700 Relay test
(No test / All OFF / Relay output QX23 Module 1 / Relay output QX21 module 1 / Relay output QX22
module 1 / Relay output QX1 / Relay output QX2 / Relay output QX3 / Relay output QX4 / Relay output
QX5 / Relay output QX6 / Relay output QX23 Module 2 / Relay output QX21 Module 2 / Relay output
QX22 Module 2 / Relay output QX7)
Warning:
During testing of an output, the heat pump is stopped,
all outputs are "off" and only the controlled output is
on.
