Input / Output Testing Functions - Fujitsu Waterstage WS G140DC6 Series Maintenance Document

Split system (Single phase and 3-phase type)
4.3.14
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
Line no. Programming line
7700 Relay test
This consists of instructing the regulator's relays one by one and checking their outputs. This enables you
to check that the relays are working and that the cabling is correct. Check that each appliance in the
installation is operating correctly.
(0) No test, (1) Everything is on STOP, (2) Relay output QX1 : heat pump CC1 (Main regulation board), (3)

module 2, (19) Not used, (20) Not used, (21) Not used.
The display shows the "Key" symbol. Pressing the Info button displays "Error 368".
Warning: The component being tested is receiving electrical power throughout the test.
Warning:
During testing of an output, the heat pump is stopped,
all outputs are "off" and only the controlled output is
on.
