Product Overview
The EP3 Series combines a microcontroller with high performance, low power coil poppet valve technology to
create a system with unparalleled accuracy and proven reliability. The poppet valves used in the EP3 consume
no air, eliminating unnecessary air losses in the system and allowing for ecient, long-term operation. The EP3
permits versatility, since all models feature manual override and a tri-state control option. The LCD provides easy
visibility and the LED indicators provide visual status of valve operation in manual or automatic mode. All models
come with SnapTrack housing and optional covers are available

Special Instructions PWM Mode
To set the minimum pulse value, adjust the Input and Setting switches as shown:
4-20mA
Voltage
Tristate
PWM
Network
Control
INPUT
Tristate Timing
Network
FS Point
Zero
RUN
SETTING
"LO" momentarily appears on the LCD, indicating that the minimum pulse width is being set. Use the (+) and (-) buttons to
increase or decrease this value. To set the maximum pulse width push both buttons simultaneously. "HI" momentarily appears,
indicating that the maximum pulse width is being set. Push both buttons to toggle between the "HI" and "LO" settings. To save
these settings, move the Setting slide switch to RUN.
If the controller receives a pulse that is shorter than the minimum pulse width, the output goes to 0% of the range set with the
zero and span settings. If the controller sees a pulse that is the same or longer than the maximum pulse width, the output goes to
100% of the range selected with the zero and span settings.
In this example the minimum pulse width is set to 0.60 sec, the maximum is set to 10 sec, zero is set to 0, and span is set to 10 psi.
Assume the controller receives a pulse of 5 sec duration:
Pulse range = 10 sec – 0.60 sec = 9.4 sec
Pressure range = span – zero = 10 – 0 = 10
Output = (5 / 9.4) x 10 = 5.3 psi
Tristate Mode
Traveltime is dened as the contact closure time required to go from zero to full scale. If traveltime is set to 10 seconds and
the TRISTATE 1 input is connected to ground for 5 seconds, the output is 50%. If the input is connected to ground for another 5
seconds, the output is 100%. If TRISTATE 2 (the decreasing input) is grounded for 10 seconds, the products output return to 0%.
To set the travel time, adjust the Setting and Input switches as shown:

RUN
SETTING
Press the (+) or (-) buttons to increase or decrease the travel time. Minimum travel time is 1 second; maximum is 600 seconds. To
save these settings, move the Setting slide switch to RUN. The device's internal counters measure the contact closure time with
100 Hz resolution.
Note: If Tristate input is to be operated by a triac output (Veris AA49), use an AC relay to provide a dry contact closure to the EP3
input.
Tubing Length
Minimum tubing length is 15 feet or an equivalent volume of 2.2 cubic inches. Shorter tubing lengths cause the unit to oscillate.
Analog Output
The output is generated from the branch pressure. It is calculated as follows:
FS = Full Scale Point
Zero = Zero setting
In volt mode:
Pressure = (10 / (FS - Zero)) * Voltage + Zero
Voltage = (Pressure - Zero) / (FS - Zero) * 10
In current mode:
Pressure = (FS - Zero) * ((Current - 4) / 16) + Zero
Current (in mA) = ((Pressure - Zero) / (FS - Zero)) * 16 + 4

Examples:
Zero setting = 5 psi; Span = 20 psi; Branch pressure = 16 psi
Volt mode: Voltage = ((16 - 5) / (20 - 5)) * 10 = 7.33 V
Current mode: Current = ((16 - 5) / (20 - 5)) * 16 + 4 = 15.73 mA
Alarms
Auto Mode: Alarm contacts are closed in normal operation and are open when no power is applied or when the device is in an
alarm state.
Manual Mode: Alarm contacts are open in manual mode setting and closed for normal operation. Move the P-LOSS/MAN jumper
to the manual mode setting. You do not need to power cycle the product after moving jumpers.
Pressure Loss Alarm: Contacts open when the branch pressure falls and stays below 20% of the desired pressure for a period of 2
minutes.

To set the Zero or FS point, move the SETTING slide switch from Run to Zero or FS point setting, respectively.
