Bell Running - Indicates that Drive air pressure is being supplied to the bell.
High Voltage Ready (HVRDYB) - Indicates interlock is satisfied, High Voltage Reset
is not active and neither Over Current Fault or Feedback Fault is present. In High
Voltage Ready mode, a signal to the High Voltage ON input will cause High Voltage
to come on.
High Voltage On (HVONB) - Indicates High Voltage is on.
Over Current Fault or di/dt Fault (OLB) - Indicates either the DC output current has
exceeded the setpoint or the current rate of rise has exceeded the di/dt sensitivity
setpoint.
Feedback Fault (FBFLTB) - Indicates abnormal signal levels are present on the kV
and/or Current Feedback signals from the cascade.
(See “Diagnostic” in the “Operation” section for a detailed description.)
Local (LOC) - Indicates front panel switch is in “Local” position. In “Local”, the set-
points for kV and Current are received from the front panel controls and not from
remote inputs.
Sequence (SEQB) - Indicates Sequence rotary switch is in a “Non-Zero” position.
(Sequence Mode Timing Diagram is shown in Figure 4.)
Fluid Trigger Active (FLTRIGB) - Indicates the Fluid Trigger output to the EFM gun
is active; applies in both sequenced and non-sequenced modes.
Air Trigger Active (AIRTRIGB) - Indicates Air Trigger output to EFM gun is active.
Overspeed Fault - Indicates module has shut down drive to bell because speed is
10 krpm above setpoint.
Underspeed Fault - Indicates module has shut down drive to bell because speed is
5 krpm under setpoint.
Loss of Feedback Fault - Indicates module has shut down drive to bell because the
maximum time allowed between feedback pulses has been exceeded.
