Display
The EDA has two displays: a lower larger display and a smaller upper display. The Home Display is the normal display
while the control is in operation if there are no errors or functions active. The Home display will indicate the process
variable at the current condition with the lower display and the selected pressure units for the process variable with
the upper display. When programming the unit both displays are also used. The Programming Chart in this instruction
manual indicates what both displays show while programming the unit. For programming descriptions in this instruction manual the format used is “lower display – upper display”. For example Ctrl – 1SP shows that Ctrl would be in the
lower display and 1SP would be in the upper display.
When the user presses the E key to edit an item’s value the upper display will flash “EDIT” and the lower display will
blink. When the user presses the E key to then save the edit to the value the upper display will flash “SAVE” and the
lower display will stop blinking.

1.0 INSTALLATION
1.1 UNPACKING
Remove the EDA from the shipping carton and inspect for damage. If damage is found, notify the carrier immediately.
1.2 MOUNTING
The EDA can be pipe, panel, or surface mounted. For pipe mounting thread the unit into a mating female fitting on the
pipe. Use a wrench on the 3/4˝ hex at the base of the housing to tighten the unit to the mating fitting. Do not thread the
unit in by force on the housing. For panel mounting, insert the unit into the panel opening and secure in place with the
machine screws and adapters provided with the unit as shown in Figure 1 below. Maximum panel thickness is 1/8” (3.5
mm) with supplied screws. For surface mounting, panel mount the unit into the A-EDA-BRK mounting bracket (See the
Dwyer catalog or website for ordering details) also shown in Figure 1. The unit can also be directly surface mounted,
as shown in Figure 2, with the proper panel cutout for the conduit entrances. Support the pressure connection hex with
a wrench if attaching a fitting to the unit in the case of panel or flush mounting so that the pressure connection does not
twist. Use a small amount of plumber’s tape or other suitable sealants to prevent leaks around fitting.

1.3 ELECTRICAL CONNECTIONS
DANGER
CAUTION
CAUTION
ELECTRIC SHOCK HAZARD. DISCONNECT POWER BEFORE MAKING ELECTRICAL
CONNECTIONS. Failure to do so will result in injury or death.
EQUIPMENT DAMAGE. Do not exceed the specified supply voltage rating. Failure to do so may
result in permanent equipment damage.
EQUIPMENT DAMAGE. Do not allow wire to touch or press on PCBA components when fishing
wire through the conduit connection. Failure to do so may result in damage to the circuitry.
To maintain Type 4X rating of the enclosure, 1/2 NPT conduit fittings must have a UL Type 4X
outdoor rating.
Note: Installation must be made in accordance with local codes and regulations.
NOTICE
Electrical connections are made to the removable terminal blocks inside the enclosure. Remove the top back cover,
do not remove bottom cover. Feed stripped and tinned leads through the conduit opening and connect them as shown
in Figure 3. The EDA provides two 1/2˝ NPT female ports for conduit connection. The conduit connections must be
made such that condensation is not allowed to enter the sensor housing. If necessary install a conduit breather drain
in a separate conduit body to prevent buildup of moisture. It is recommended that shielded twisted pair wire be used
for the transmitter output option if the potential exists for interference from external noise sources. When replacing top
back cover tighten screws to 2 ±.25 in. lbs.

Loads can be connected to connectors CONN7 and CONN8 terminal blocks based on the Control settings:
• For single set point mode (CtrL-1SP), connect the Load to SP1 relay (CONN7).
• For two set points mode (CtrL-2SP), connect the Load1 to SP1 relay (CONN7) and
Load2 to SP2 relay (CONN8).
• For single set point and alarm mode (CtrL-SPAL), connect the Load1 to SP1 relay
(CONN7) and Load2 to ALARM relay (CONN8).
Wiring
An external switch or circuit breaker should be added to during the installation as a disconnecting device. The switch
or circuit breaker must meet the requirements of IEC 60947-1 and IEC 60947-3, shall disconnect all current carrying
conductors, and shall not interrupt the protective earth ground. The disconnecting switch or circuit breaker must be
marked or labeled with the symbols “I” for on and “O” for off, per IEC 60417-5007 & IEC 60417-5008 and shall be
marked as “Disconnecting Device”. Do not position the PLS in a space where it is difficult to operate the disconnecting
device that provides power. 300V @ 90°C 18 AWG/0.75 mm2 wiring with PVC or equivalent insulation with 94-V0 or
FV-0 flammability rating is recommended for the switch outputs and power. Terminal blocks rated for 16-22 solid or
stranded copper conductor. 6 lb in is suggested tightening torque.

­­2.2 SET POINTS & ALARMS
Setting Set Points and Alarms
The
hot key provides direct access to the Set Point and Alarm settings.
The Set Point and Alarm settings that are displayed are based upon the Control (CtrL) menu item.
Set Point Adjustment
Adjusting the set points is quick and simple. Instead of setting a set point and dead band, simply adjust SP1H, Set
Point 1 High, and SP2H, Set Point 2 High, for the desired relay turn on point, and then adjust SP1L, Set Point 1 Low,
and SP2L, Set Point 2 Low, for the desired relay turn off point.
In the above graph, an instrument with a 100 psi range would have the SP1 relay turn ON at 80 psi and OFF at 40 psi.
SP1H sets the relay turn ON point, and SP1L sets the relay turn OFF point.
7
Relay Action
The relays outputs normally function in the direct acting mode, which means the relays turn ON with an increase in
pressure. SP1 and SP2 may be configured to act as reverse acting relays (refer to the CtrL menu item). When set for
reverse acting, SP1H and SP2H set the relay turn OFF point, and SP1L and SP2L set the relay turn ON point. The
above graph demonstrates direct and reverse action on process (pressure) change.
Alternating (Lead/Lag) Operation
The EDA is designed to easily operate a pair of pumps in an alternating operation to minimize pump wear. The unit has
programmable on and off set points for pump one and two. If the lead/lag feature is turned off then the relays remain
attached to their corresponding set points, SP1H and SP1L control relay 1 (pump 1) and SP2H and SP2L control relay
2 (pump 2). There is no alternating function.
If lead/lag feature is turned on then the relays will alternate with set points SP1H and SP1L to SP2H and SP2L with
every cycle of set points. The Last relay turned off will be last relay turned on with the next cycle. On the first cycle
on increase of pressure, assuming direct acting, the SP1 relay (pump 1) will come on and then on further increase of
pressure the SP2 relay (pump 2) will come on. On the subsequent decrease of pressure the SP2 relay (pump 2) will
come off and then the SP1 relay (pump 1) will come off. When pressure increases on the next cycle the relay used
on the last cycle for SP2 will now be used for SP1, so that SP1 now controls pump 2 and SP2 now controls pump 1.
Even if SP2 is not used on the pressure cycle the relays still alternate on next cycle. 8

diS Display Menu
PEAK
Peak
The Peak feature stores the highest pressure reading the instrument has measured since the last reset or
power up. At power up PEAK is reset to the present pressure reading. To manually reset the PEAK value,
press the RST (RESET) key while in PEAK.
VALY
Valley
The Valley feature stores the lowest pressure reading the instrument has measured since the last reset
or power up. At power up VALY is reset to the present pressure reading. To manually reset the VALY
value, press the RST (RESET) key while in VALY.
DAMP
Dampening
Adjust from 1-15. Dampening stabilizes the display from instabilities due to things such as vibration
and excessive pressure fluctuations. The dampening setting adjusts the amount of readings that are
averaged for each display update. Adjust the dampening value until the display reads a stable value for
the application.
AdU Advanced Menu
POL, Process Output Low, and POH, Process Output High are used to scale the transmitter output for a unit with the
