POWER ON
1. Relays K1 on both the C-arm and Workstation B111 boards energize
when either the C-arm or Workstation "On Switch" is pressed.
2. Power relay K1 in the C-arm and power relay K3 in the Workstation
then energize allowing AC power to the C-arm T1 and Workstation T1.
The initial input current is limited by R1 in both the C-arm and Workstation.
3. Approximately 70ms later the power relays K2 in both the C-arm and
Workstation energize, allowing the input current to bypass the current
limit resistor R1.
POWER OFF
1. Relays K1 on both the C-arm and Workstation B111 boards de-energize
when either the C-arm or Workstation "Off Switch" is pressed.
2. Power relay K1 in the C-arm and power relay K3 in the Workstation then
de-energize shutting off AC power to both the C-arm and Workstation
T1 transformers.
