Display and Diagnostics of the High Speed Counting Function

Description

The HSC counting module has LEDs that enable the status of the module to be viewed.

The LEDs for inputs/outputs of each channel are:

State LED for inputs of each channel: IA, IB, IS, IE, IP, IC.
State LED for outputs of each channel: Q0, Q1.

Representation

The below figure shows the LED indicator of the HSC function:

Function Diagnostics

The following table presents the various function states according to the LED states (empty cell indicates that the pattern on the associated LED can be ignored):

LED indicators								Function Status
IA	IB	IS	IE	IP	IC	Q0	Q1	Function Status
BLK					-	-	-	Sensor supply fails
-	-	-	-	-	-	BLK		Actuator supply fails

Legends
ON								LED is turned on
OFF								LED is turned off
FLK (Flickering)								The LED is turned on for 50 ms then turned off for 50 ms
BLK (Blinking)								The LED is turned on for 200 ms then turned off for 200 ms
