2.1.4 Electric Wiring Work and Initial Setting
1. Wiring
2. Depending on whether [voltage input] or [non voltage input], connect the wiring as shown below.
„
Input with Voltage.
Set the Voltage/Non voltage changeover switch (SS1) to VOLT.
„
Input with No Voltage.
Set the Voltage/Non voltage changeover switch (SS1) to NON VOLT.
3. Display signal retrieval (Output)
The normal operation output terminals (W1, W2) and error output terminals (W3, W4) are non-voltage output contacts.
(Permissive current is 10mA~3A per contact.)
Output is as given below.
Output
Both Ry1 and Ry2 is OFF. Only Ry1 is ON. Only Ry2 is ON.
System
Group control OFF All normal operation
At least one unit is stopped due to error or transmission error
between the adaptor and the indoor unit.
Normal operation
output (Ry1) ON
during normal
operation
Error Output (Ry2)
"ON" when the operation
is stopped by
malfunction, or when
there is a transmission
error between the adaptor
and the indoor unit.
DC24V
AC24V
AC100V
AC200V
Cautions: If using 100VAC or
200~240VAC, the power wiring
should be separated from the
input wiring.
