RC1/
SLOW
Relay KM3 (MCU Output 3): N.O. contact; Default: Main contactor (Running
contactor)
Note: For lifts with safety unit for moving with open doors the relay KM3 must
always be used as running contactor even if nothing is connected to KM3,
because by a second contact of KM3 the door zone bypass will be enabled.
DOWN
Relay KM2 (MCU Output 2): N.O. contact; Default: Downwards contactor
FAST
Relay KM1 (MCU Output 1): N.O. contact; Default: Fast contactor
V2*, V2
Relay KM1 (MCU Output 1): Additional, potential free N.O. contact
XM5
L-SAF
Connection for end of safety circuit to switch contactors
N-SAF
Neutral safety circuit (Output to connnecting neutral to contactors)
SDSL
State input safety line shaft doors (MCU Input 12), for 110V to 230V AC
CDSL
State input safety line car doors (MCU Input 11), for 110V to 230V AC
RDSL
State input safety line revolving shaft doors (MCU Input 10), for 110V to 230V
AC
PSL
State input primary safety line (MCU Input 9), for 110V to 230V AC

SRO
Safety circuit door zone bypass for moving with open doors (output of safety
unit SRU)
XM7
0V
0V – Power supply (to trailing cable)
+24A
Battery buffered 24V power supply (to trailing cable); Imax. = 1.0A (electronic
fuse on MCU)
