Internal Variables
70 ID_PROFILE_STATE
This is the run state of the prole.
• 0 => STOP
• 1 => START
• 2 => RUN
71 ID_PROFILE_STEP
This is the step in the prole which is currently being run.
119 ID_UI_PROFILE_STARTRUN
This is the restarting mode of the prole.
• 0 => Restart prole at the beginning
• 1 => Resume prole at current prole step
ER5000 Single “Puff” Solenoid Control Variable
73 ID_PULSE
This variable allows opening the inlet or exhaust for the
specied duration for one pulse period. After one pulse
duration, the variable is returned to a value of 0.
• 0x08fa => Inlet full open
• 0x0800 => Both valves closed
• 0x0706 => Exhaust full open
ER5000 Pulse Mode Variables
81 ID_PULSE_PERIOD
This controls the rate of the pulse while pulse mode is active.
The value represents how many passes through the control
algorithm (25 ms per pass) before sending a pulse to one of
the solenoids.
82 ID_PULSE_WIDTH
This controls how long the solenoid is held open while pulse
mode is active. Part of this number compensates for allowed
system uctuations (or noise) so too small a number will not
open the solenoid valve.
83 ID_PULSE_DEADBAND
This is the error from the setpoint allowed for the pulse
function to stop pulsing. This value is in counts read up
from the sensor. One count of error is .03% and typically this
number is in the range of 0–3.
84 ID_PULSE_ENABLE
This turns the pulse function ON(1) or OFF(0).
