FUNCTION FUNCTION FUNCTION FUNCTION FUNCTION
This instrument can use the input "IN CT/SP-
SP2" (connections 14 and 15) as current
transformer input or a logic input.
The current transformer input allows to measure
and display the current running in the load driven
by the OUTPUT1 during the ON and OFF period
of the OUT 1 cycle time. By this feature it is also
available the "OUT 1 failure detection" function
(see page 20). The logic input is used to switch,
by an external contact, from main set point to
second set point and viceversa.
To select the desired input type, set J504 as
detailed in the figure shown below:

FUNC = This will memorize the new value of
the selected parameter and go to the
next parameter (increasing order).
MAN = This will scroll back the parameters
without memorization of the new value.
= This will increase the value of the
selected parameter
= This will decrease the value of the
selected parameter.

CONFIGURATION PROCEDURE
