Description
Used to reset fault output provided when a fault occurs.
Turn ON the RES signal for more than 0.1s, then turn it OFF.
Turning ON the SOF signal stops the converter.
RDY signal turns OFF, limit MC turns ON
200V class
Connect this terminal to terminal ROH1 of the
7.5K to 75K
outside box (FR-HCB2). The ROH signal is
400V class
input to stop the converter operation when
7.5K to 220K
the limit resistor may overheat.
An auxiliary contact (NO contact) of a limit
resistor MC, a limit resistor (with thermostat)
(NC contact), and a filter capacitor alarm
400V class
detector (NC contact, 400K, 560K) are
280K to 560K
connected to stop the converter operation
when overheating of the limit resistor
becomes a concern and when a filter
capacitor is faulty.
FM and AM output or PU monitor display can be switched by a
combination of ON/OFF of X1 signal and X2 signal.
Common terminal for contact input terminal (sink logic) and terminal
FM.
When connecting the transistor output (open collector output), such
as a programmable controller in source logic, connect the external
power supply common for transistor output to this terminal to
prevent a malfunction caused by undesirable currents.
Common output terminal for 24VDC 0.1A power supply (terminal
PC).
Isolated from terminals 5, SE and SE2.
When connecting the transistor output (open collector output), such
as a programmable controller in sink logic, connect the external
power supply common for transistor output to this terminal to
prevent a malfunction caused by undesirable currents.
Common terminal for contact input terminal (source logic)
Can be used as 24VDC 0.1A power supply.
