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. 34 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.

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. 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 (-HV option must be 120-240 VAC). 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 EXTERNAL POWER TO CONN10 TERMINALS - PERMANENT DAMAGE NOT COVERED BY WARRANTY WILL RESULT. 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 EDA in a space where it is difficult to operate the disconnecting device that provides power. 300 V 18 AWG/0.75 mm 2 wiring with PVC or equivalent insulation with 94-V0 or FV-0 flammability rating is recommended for the switch outputs and power. Use only copper wire rated to 60°C minimum. Terminal blocks rated for 16-22 solid or stranded copper conductor. 6 lb in is suggested tightening torque. 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 easy reach of the operator. This disconnect device must include a label indicating its function as a mains disconnect. A circuit breaker or fuse device is recommended (see Figure 3).

DISCONNECT POWER BEFORE MAKING ELECTRICAL CONNECTIONS. Failure to do so will result in injury or death. DANGER To maintain Type 4X rating of the enclosure, 1/2 NPT conduit fittings must have a UL Type 4X outdoor rating. NOTICE 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. CAUTION EQUIPMENT DAMAGE. Do not exceed the specified supply voltage rating. Failure to do so may result in permanent equipment damage.

OPERATING INSTRUCTIONS 2.1 FRONT PANEL & KEY FUNCTIONS Figure 4: Front panel functions7 2.2 SET POINTS & ALARMS 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. 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.Next >
