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.

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
hread the unit in by force on the housing. For panel mounting the unit fits into a 4-13/16” (122.24 mm) panel cut out.
t
nsert the unit into the panel opening and secure in place with the machine screws and adaptors provided with the
I
nit as shown in Figure 1 below. Maximum panel thickness is 1/8” (3.5 mm) with supplied screws. For surface mount-
u
ing, panel mount the unit into the A-370 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.

AUTION: To maintain type 4X rating of the enclosure, 1/2 NPT conduit fittings must have a UL type 4X out-

oor rating.
d
Note: Installation must be made in accordance with local codes and regulations. When fishing wire through the conduit
onnection do not allow the wire to touch or press on components on the boards. Damage to the circuitry may result.
c
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 sep-
rate conduit body to prevent buildup of moisture. It is recommended that shielded twisted pair wire be used for the
a
ransmitter output option if the potential exists for interference from external noise sources. When replacing top back
t
cover tighten screws to 2 ±.25 in. lbs.
Figure 3: Wiring
An external power supply of 12-28
VDC/AC with minimum current capability
of 200 mA must be used to power the unit.
The power supply connection is not polarity sensitive so the positive and negative
connections may be made to either terminal of CONN9 terminal block.
For voltage output option, connect the voltage receiver (-) to terminal 1 and voltage
receiver (+) to terminal 2 of the CONN10
terminal block. For current output option,
connect the current receiver (-) to terminal
3 and current receiver (+) to terminal 4 of
CONN10 terminal block. DO NOT APPLY

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 mm
2
wiring with PVC or equivalent insulation with 94-V0 or FV0 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.
WARNING
easy reach of the operator. This disconnect device must include a label indicating its function as a mains disconnect. A
As a permanently installed piece of equipment, a power disconnect switch, circuit breaker, or other
approved disconnect device must be installed in close proximity to the installed board and within
circuit breaker or fuse device is recommended (see Figure 3).

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.
Setting Set Points and Alarms
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.
