FAULTS AND WARNINGS

The Mini-GL constantly monitors its sub-systems. The following are conditions that may interfere with 'normal' system
operation and will display a warning or fault message. Note the "C" and "W" indicates a CAL or Warmup is required.

5.1 HV sample does not settle to within +-8 volt at End of Charge (EOC) within 1.5 seconds.
5.2 HV sample is not within +-3% of HV reference when HVPS is at EOC.
5.3 HV sample is not within +-3% of HV reference after DCD pre-spray already occurred.
6.1 CAL Low slope point not in range of 500V to 1800V.
6.2 Expected Head Energy (xHD) is calculated > Max HD Energy of 75 J.
6.3 Laser failed to CAL to desired Fluence within 25 pulses.
6.4 CAL required a HV > 2000V for desired Fluence.
7.1 DI temp < 60degC when not in warm-up.
7.2 DI temp > 70degC while in Ready state.
DI pressure switch does not change when power turned on. OR
7.3
DI pump is not ON or DI pressure switch not actuated.
DI temp < Thermistor Open Temperature (5) OR
7.4
DI temp > Thermistor Shorted Temp (98) while in Ready state

9.1 DI temperature < 62degC after 60 minute warm-up
9.2 DCD pressure < 105psi after 60 minute warm-up (Only when DCD enabled)
10.1 HP type changed or unrecognized while in Ready (15 consecutive reads at 50 ms interval)
10.4 Fiber not detected while in Ready (15 consecutive reads at 50 ms interval)
10.5 Slider button pressed while in Ready State. Cannot change spot-size while in Ready.
12.1 On last treatment pulse, the head energy (HD) was 14% lower than expected head energy (xHD). C
12.2 On last treatment pulse, the head energy (HD) was 14% higher than expected head energy (xHD). C
12.3 The head energy (HD) of the last pulse > Max Treatment HD Energy of 75 J.
13 The redundant trigger switches were in two different states for > 1 second while in ready.
15.1 Transmission (Tx) is < 70%. (HD or CP energy > 5.0 J)
15.2 Transmission (Tx) is > 100%. (HD or CP energy > 5.0 J)
DESCRIPTION
Displays once when DCD Canister Pulse count = 0
Displays if canister bubble is detected in Ready and DCD is enabled.
Bubble percentage is outside of tolerable range (~15% bubbles).
Transmission is < 75% - Delivery system degrading - Clean Window
