Safety edge
input
X1, X2
Connect to SGE Safety Edge.
Connect a 2-wire cable to SGE Safety Edge. There is no polarity.
Manual/
auto reset
switch input
S11, S12
Switch between auto reset and manual reset.
• For auto reset, open the terminal between S11 and S12 (Default setting)
• For manual reset, short-circuit the terminal between S11 and S12.
DC power
supply input
B1, B2
Power supply input terminals to be used with DC power supply.
Open when using them with AC power supply.
Reset
input
Z1, Z2
Input terminals for reset switch (NO contact)
.
Connect to pushbutton switch or key switch.
They do not need to be connected for auto reset mode.
AC power
supply input
A1, A2
Power supply input terminals to be used with AC power supply.
Open when using them with DC power supply.
Auxiliary
output
31-32
• SCC-1224
Operates as one-shot delay timer that closes contacts after
power is turned ON or when the SGE safety edge operates,
and open after 2 seconds or less than 3 seconds.
• SCC-1224ND
Contacts close when the SGE safety edge operates, and keeps
closed until the safety edge returns to its normal operation.
Open when not used.
Do not use this contact for safety circuits.
Safety
output 1
13-14
Turn the output ON or OFF according to safety edge inputs and
reset inputs.
Open when not used.
A jumper is set between terminal 14 and 23 in the default settings.
Remove the jumper if safety output 1 and 2 are not connected in
series.
Safety
output 2
23-24
Name
Description
Power supply LED
indicator (Green)
Lights when the power supply is ON.
Active LED indicator
(Yellow)
Lights when pressure is applied to the SGE safety edge, blinks during interlock state.
When pressure is released, the interlock is reset and turned OFF.
Error LED indicator (Red)
Lights when a wiring error of the safety edge occurs such as cable disconnection
of the SGE safety edge, contact failure of terminal X1 and X2 of the SCC edge controller,
or when a terminating resistor is not connected to the safety edge.
Auxiliary output LED
indicator (Orange)
Lights when pressure is applied to the SGE safety edge, and blinks when an auxiliary output contact is closed (auxiliary output ON)
.
SCC-1224: Lights OFF after 2 seconds or more/less than 3 seconds.
SCC-1224ND: Keeps ON while pressure is applied to the SGE safety edge.
