DANGER:
RISQUE DE MORT OU DE BLESSURES CORPORELLES. Débrancher et
verrouiller/étiqueter toutes les sources de puissance d'entrée avant de
travailler sur cette unité ou sur tout élément qui y est raccordé.
DANGER:
Personnel must receive proper training before installing or troubleshooting
high-energy electrical equipment. Potentially lethal voltages could cause
death, serious personal injury, or damage to the equipment. Ensure that all
appropriate safety precautions are taken.
DANGER:
Le personnel devra être correctement formé avant de pouvoir installer ou
dépanner des équipements électriques à haute énergie. Des tensions
potentiellement létales peuvent entraîner le décès, des blessures ou des
dommages à l'équipement. Assurez-vous de prendre toutes les précautions
de sécurité appropriées.

No LEDs Lit

If no LEDs are lit, check for these errors:
• The customer-supplied power supply for the A70 control device is missing.
• Check that the voltage at terminal X1.1 and X1.2 of the A70 control device is
within the range 90 VAC to 265 VAC, or that X3.1 and X3.2 are at 24 VDC.
• Check that fuses F2 and F3 on the A1, A3, and A5 controller cards are not
open.
• Check that the semiconductor load fuses are not open.
• For transformer loads, the phase angle of the first half-wave might need to be
optimized. Begin with a phase angle (phase angle 1) = 60 degrees, and slowly
increase until the inrush current is minimized.

No Load Current

Check the following if no load current is present:
• Supply voltage of the A70 control device is within the range 90 VAC to
265 VAC, or X3.1 and X3.2 are at 24 VDC.
• Pulse lock X51.3 is jumpered to X51.2.
• Setpoint is available and active. Using the display or software, check the total
setpoint (effective total), or measure setpoint on X52.2 and X52.5.
◦ Setpoints are not cleared.
