Table 6. EC-SCB Input Connector Descriptions: J1, J2, J3, J4
Terminal No. Function Remark
J1
S6 Step Sensor #1 S6 and S7 monitor direction, step speed,
and missing steps for Sensors #1 and #2
respectively.
S7 Step Sensor #2
S8
Left handrail speed
monitoring
Impulse input. Frequency between 0.5-
25HZ
S9
Right handrail speed
monitoring
J2
P26 Safety circuit
Low = Open safety, run disabled
High = Safety OK, run enabled
P27

open the safety string, stopping the esca-
lator. Under fault conditions, there will be
+24V at these terminals.

Lower right skirt
obstruction detection
P29
Lower left comb-step
impact detection
P30
Lower right comb-step
impact detection
P31
Lower left handrail
entry detection
P32
Lower right handrail
entry detection
P33
Lower step level
detection
J3
P34
Lower step upthrust
detection
P35 Lower stop switch
P36 Spare input
Some LCD software versions allow an
error message to be programmed for dis-
play when P36 is activated: Broken step
chain, Tandem fault, Broken belt, Brake
wear, Pit flooded, Brake overheat.
Program using parameter F4-18.
P37 Spare input
Some LCD software versions allow an
error message to be programmed for dis-
play when P37 is activated: Pit flooded,
Tandem fault, Broken belt, Brake wear,
Broken step chain, Brake overheat.
Program using parameter F4-19.
P38 Lower entry detector
Active with VVVF drive when energy sav-
ing mode is selected.
