Jumper Configuration
Input Current (4-20 mA) or Voltage (0-5 V or 0-10 V)
Voltage For voltage mode of operation, select 0-5 V or 0-10 V
Pressure Range Select 0-20 psi or 3-15 psi scaling
Operation Mode Select AUTO for normal operation or MANUAL to adjust pressure
using the pushbuttons
Options
Alarm Mode Relay The alarm contacts open if the EP2 cannot obtain 80% of
commanded pressure within two (2) minutes
Manual Mode Alarm Contacts open when manual mode is selected (auto mode contacts
are closed)
Vent On Power Fail The EP2 vents the branch line pressure on power failure
Terminal Block Connections
GND/Common Power supply ground and signal common.
Input Signal 4-20 mA, 0-10 VDC, or 0-5 VDC input from the control system.
Power 22-30 VDC, 20-30 VAC. From the control system or external power
supply or transformer.
Pressure Loss
Alarm (optional)
Normally closed, solid-state contacts open if the main supply pressure
fails or if the transducer is otherwise unable to produce the correct
branch pressure. Connect to the digital input of the control system for
alarm status indication. If commanded pressure does not reach 80%
within 2 minutes, the alarm contacts open.
• 0-20 psi alarm contact does not change state when the
commanded pressure is 4 psi or less
• 3-15 psi alarm contact does not change state when the
commanded pressure is 5.4 psi or less
NOTE: In 24 VAC transformer applications, one side of the transformer secondary is connected to
the signal common. Some control systems may require a dedicated power supply transformer or
isolation transformer.
