INSTALLATION

Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty.

1. Mount the EP3 transducer using the screws provided.

2. Congure the jumpers for desired operation as shown (page 2).

3. Wire the transducer as shown in the wiring diagram (page 3).

4. Attach pressure tubing to the hose barbs. Observe MAIN and BRANCH port labels. Use exible 1/8” I.D. poly tubing for main and branch pneumatic connections.

Main supply pressure must not exceed 45 psig.

CONFIGURATION

Switch/Jumper Description

Input User selectable slide switch: current (4-20 mA), voltage (0-5/0-10

V), Tristate, or PWM (min 0.01-0.60 sec, max 1.0-75.0 sec).

Note: the Network Control option is disabled.

Input Voltage* If voltage input is selected, use this jumper to choose 0-5 or 0-10 V.

Tri Pull-up If tristate input is selected, use this jumper to turn the pull-up on

or o.

Alarm Phase loss or manual

Output Use this jumper to select 4-20 mA or 0-10 V output (feedback status

for branch pressure.

Setting User selectable slide switch: Tristate timing (min 1 sec; max 600 sec,

default 60 sec), FS Point (scale point user programmable 0-25 psi), Zero (user programmable 0-25 psig), Run.

Note: the Network option is disabled.

Mode Auto for normal operation; Manual to adjust pressure.

Set this switch last.

* EP3 accepts DC input only. To use with AC input, include a Veris AA49 Triac Adapter in series between the input voltage a nd the EP3.
