SERVICE INFORMATION
CURRENT RELAY SETTINGS
This service information contains information about the settings
and replacement of the current relays, used for low current
alarm of the heating.
The manufacturer has changed the design in June 2004 and
due to this the settings of the relay have been affected.
DIB01 current relay
Note!
From June 2004 the SJ155 is replaced by the new DIB01 relay.
Supply connection
For the DIB01 relay the supply connections are 11 and 10, for
24 VAC. See illustration 1.2.
Replacement
On some equipment the 1 - 5 A relay is installed with an exter-
nal shunt resistor. When replacing this relay, make sure to
remove the shunt resistor and use the 10 A version of the new
relay.
Setting
Set the front potentiometers as follows:
HYS = 10%
LEVEL = Current
DELAY = 1-3 sec.
To access the DIP switches open the grey plastic cover. Set the
DIP switches to the
!
-marked value, according to illustration 1.3.
