I/O Integration
NOTE:
The EFR software con5V as ON, which
means the +5V supply on pin 3 of connector 4 can also
be used as an external source to trigger digital input
pins ON.

Digital Input:
• 5-24V is ON

Trigger Signal
: When this digital input pin is pulsed ON by an exter
-
nal source or a foot switch, the EFR system will run the active
sequence.

Pressure Preset (Priming):
When this digital input pin is ON, the
EFR system will run the pressure preset procedure, and when this
digital input pin is OFF, the pressure preset procedure will be
stopped.

System Enable:
When this digital input pin is ON, the EFR system
will be active, and when this digital input pin is OFF, the EFR system
will be inactive.

Analog Input:
• 0-10V Analog Range
Analog Flow Rate:
This Analog Flow Rate is only used when a
sequence is in operator mode. The flow rate put into the operator
mode will correspond to a 10V signal. Then a linear scale is used to
scale across the analog range, with 0V being 0 flow.
Example:
If the operator mode of a sequence step has a flow rate of
100cc/min and the analog flow rate signal of 5V is sent over, the EFR
will run at 50 cc/min. 10V is 100cc/min, 7.5V is 75cc/min and 0V is
0cc/min.

Digital Output:
• 5-24V is ON
• 0V is OFF
System Ready:
This digital output pin will be ON when the EFR sys

tem is ready to receive the next command. If the EFR system is dis
-
pensing, loading a sequence or the valve is open, the system ready
signal will be OFF.

Digital Output:
• 5-24V is ON
• 0V is OFF
Alarm Active:
This digital output pin will be ON when the EFR sys
-
tem has an active alarm, deviation or advisory. When there are no
active alarms, deviations or advisories, the digital output pin will be
OFF.
