Operation
Functions
Operation Mode
Relationship between G9SX-LM outputs (safety instantaneous
outputs and safety speed detection outputs) and inputs (safety input,
enabling input, rotation detection input) differs depends on mode
selector input status.
Normal operation mode (Mode selector input M1=ON, M2=OFF)
Safety instantaneous outputs and safety speed detection outputs
condition turn on depending on rotation detection input condition.

Note: 1. When the logical AND preset switch is set to AND (enabled),
the logical AND connection input must be ON for the safety
instantaneous output to be turned ON.
2. Safety instantaneous outputs turn on when the feedback
reset inputs condition satisfies its condition and above
stated one. Reset mode (auto reset or manual reset) shall
be selected depending on the application.
Logical AND Connection
The logical AND connection means that the Basic Unit (or Advanced
Unit) outputs a safety signal "a" to an Advanced Unit, and the
Advanced Unit calculates the logical multiplication (AND) of the safety
signal "a" and safety signal "b." The safety output of an Advanced Unit
with the logical AND connection shown in the following diagram is "a"
AND "b".

Datasheet".
G9SX-LM
Low-speed Detection Function
Converts the pulse signals from two proximity sensors that monitor
the rotation status of hazards to frequency to control the safety speed
detection outputs.
• The diagram below shows the relationship between the Low-speed
detection frequency and Safety speed detection outputs. The
frequency (F) has a tolerance of - 10%.
• This accuracy tolerance does not include any characteristics of
proximity sensors.

(Time)
Use the following OMRON E2E series three-wire DC sensors (PNP).
E2E-X1R5F1
E2E-X2F1
E2E-X5F1
E2E-X2MF1
E2E-X5MF1
E2E-X10MF1
Note: 1. To monitor the rotation status of hazards, install a cogwheel
for proximity sensors linked to hazards as follows. For
design of cogwheel and installation of proximity sensors,
see page 13 "Shape of Cogwheel and Setting of Proximity
Sensors".

2. If G9SX-LM@ is operated without proximity sensors being
connected, G9SX-LM@ will detect it as an error.
3. If both sensors do not detect the cogwheel, G9SX-LM@ will
detect it as an error.
