Model Number Chart
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
R
emove the EDA from the shipping carton and inspect for damage. If damage is found, notify the carrier immediate-
l
y.
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 t
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.
I
nsert the unit into the panel opening and secure in place with the machine screws and adaptors provided with the
u
nit 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-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.
