APPENDIX C - USER INPUT FUNCTIONS
GS120 user inputs can be confi gured as Start/Stop controls for the traffi
c light seg-
ment, or as counter controls (if the GS120 is confi gured to run in counter mode). To
enable counter mode options,
User input 1
must fi rst be set to
Counter
in 6.4B (see
4.2 for more information on counter mode).
Input function
Description
Count direction
(Cnt Dir)
Available on
User input 2
when
User input 1
is set to
Counter
.
This option allows the
User input 2
pin to control the direction of the
count. If
User input 2
is inactive, then count pulses on
User input 1
will
cause the count to increase. If
User input 2
is active, then count pulses
on
User input 1
will cause the count to decrease.
Gated count
(Gate Cnt)
Available on
User input 2
when
User input 1
is set to
Counter
.
This option allows the
User input 2
pin to gate count pulses applied on
User input 1
. In this mode
User input 1
will only count up if
User input
2
is active. If
User input 2
is inactive, then count pulses on
User input 1
will not change the count value.
Reset count
(Rst Cnt)
Available on
User input 3
when
User input 1
is set to
Counter
.
This option allows the
User input 3
pin to reset the count. Activating
User input 3
in this mode will reset the count value to zero.
StartLED
Available on
User input 1, 2 or 3
when a traffi
c light annunciator char-
acter is installed.
The green Start light on the traffi
c light annunciator will turn on when
this input is active.
StopLED
Available on
User input 1, 2 or 3
when a traffi
c light annunciator char-
acter is installed.
The red Stop light on the traffi
c light annunciator will turn on when
this input is active.
Start/Stop
Available on
User input 1, 2 or 3
when a traffi
c light annunciator char-
acter is installed.
In this mode, the user input will act as a toggle, turning the green Start
light on when the input is active, and the red Stop light on when the
input is inactive. Where other user input pins are set to execute oppos-
ing functions (i.e. StartLED or StopLED), lower numbered user inputs
will take priority over higher numbered user inputs.
