PICO-GUARD Controller
Instruction Manual
Figure 4-3. PICO-GUARD controller status indicators
“System Status” Indicator (bi-color Red/Green): overall status of the
PICO-GUARD system
Green – Run condition
Red – Stop or Latch conditions
Red Flashing – Lockout conditions
Flashing Burst* (Red or Green) – electrical noise in the system
“System Reset” Indicator (bi-color Yellow/Red): status of the System
Reset input or System Reset needed
Yellow Double-Flashing – waiting for system reset after power-up
Yellow Single-Flashing – waiting for system reset after latch condition
Yellow – input signal is high
Red Flashing – external fault of the input detected
OFF – input signal is low or during lockout (except for System Reset
faults)
Red Flashing Burst* – noise on the System Reset input
Optical “Channel” Indicators (bi-color Red/Green): status of the optical
channels (one indicator for each optical channel)
Green – channel is closed (clear)
Green Double-Flash – channel was interrupted, but is closed again
(latch mode only)
Flickers Green – weak or marginal signal
Red – channel is open (blocked)
Red Flashing – channel fault detected
OFF – channel is disabled or during lockout (except for optical channel
faults)
Flashing Burst* (Red or Green) – noise on the channel
“USSI” Indicators (bi-color Red/Green): status of the USSI input
channels (a-b and c-d), two indicators per USSI input (one for each input
channel)
Green – an input channel is closed (high)
Red Flashing – external fault of the input channel detected
Both Synchronized Red Flashing – fault detected, but the specific input
channel cannot be determined
OFF – an input channel is open (low) or during lockout (except for
USSI channel faults)
Flashing Burst* (Red or Green) – noise on the input channel
“USSI 1 Reset” Indicator (bi-color Yellow/Red): status of the USSI 1
reset input, or USSI 1 reset needed
Yellow – input signal is high
Yellow Flashing – waiting for USSI 1 latch reset
Red Flashing – external fault of the input detected
OFF – input signal is low or during lockout (except for USSI 1 Reset
faults)
Red Flashing Burst* – noise on the USSI 1 reset input
“EDM” Indicators (bi-color Red/Green): status of the EDM inputs (one
indicator for each input)
Green – input signal is high
Red Flashing – external fault of the input detected
Both Synchronized Red Flashing – EDM fault detected; specific input
cannot be determined
OFF – input signal is low or during lockout (except for EDM input
faults)
Flashing Burst* (Red or Green) – noise on an EDM input channel
“OSSD” Indicators (bi-color Red/Green): status of each OSSD output
(one indicator for each output)
Green – OSSD is ON
Red – OSSD is OFF
Red Flashing – external output fault detected
Both Synchronized Red Flashing – specific OSSD output fault cannot
be determined
OFF – lockout (except for OSSD output faults)
“Config” Indicator (bi-color Red/Green): status of the system
configuration
Green – configuration switch state is valid
Red Flashing – configuration switch state is invalid
OFF – lockout (except for configuration faults)
* A flashing burst is three short consecutive flashes, followed by
a pause.
