Control Terminals Connection - Fujitsu Frenic Eco FRN-F1 Starting Manual

FRN-F1

3.2.1 Control Terminals Connection

Digital inputs and outputs can be operated both in NPN (sink) and PNP (source) logic.
a) DIGITAL INPUTS: Refer to the user's manual MEH456 for connection examples.
SW1 SINK SW1 SOURCE
b) TRANSISTOR OUTPUTS: Refer to the user's manual MEH456 for connection examples.
To decide what logic to use, there is no switch as before.
Connecting "PLC" terminal to the transistor common "CMY" terminal you will have PNP logic.
Connecting "CM" terminal to the transistor common "CMY" terminal you will have NPN logic.
c) RELAY OUTPUTS:
Y5A/C RELAY: you can switch its output mode between "Active ON"
(the terminals [Y5A] and [Y5C] are short-circuited if the signal is
active) and "Active OFF" (the terminals [Y5A] and [Y5C] are open-
circuited if the signal is active).
30A/B/C RELAY: switching of the normal/negative logic output is
applicable to the following two contact outputs: "Terminals [30A] and
[30C] are short-circuited for ON signal output (Active ON)" or "the
terminals [30B] and [30C] are short-circuited (non-excite) for ON
signal output (Active OFF)."
Chapter 3: Electrical Installation
The switch SW1 located on the control board defines the logic
used for digital inputs. Factory default setting is source.
? SINK LOGIC: Digital input ON giving 0 volts.
? SOURCE LOGIC: Digital input ON giving 24 volts.
