ACC2 - Internal Features

 

 

1Facepack Cable

The facepack cable connection is located beneath the status light. It is a standard connector with a locking lever on one side, which must be pressed in to remove the cable.

 

2Power Supply Board Replacement

Die Netzteilplatine oben links im Gehäuse ist eine wesentliche Komponente und verfügt über Verbindungen für externe Sensoren, Pumpen-/Hauptventilausgänge, gemeinsame Drahtverbindungen und mehr.

The Power Supply Board is also designed for convenient replacement, if necessary. Three captive screws (#2 Phillips) secure the board. Three modular wiring plugs connect the board to the controller.

 

3Earth Ground Lug

A heavy duty earth ground lug is provided for lightning and surge protection. This connection is for equipment safety only. It should always be connected with heavy copper wire to approved grounding hardware buried in the earth at least 8' (2.5 m) away from the controller.

Erdungsysteme bestehen hauptsächlich aus einem kupferplattierten Erdungsstab von 2,5 m (8‘), der vollständig unter der Erde liegt, oder einer 2,5 m x 1,25 m (8' x 4‘) breiten Kupferplatte oder beidem oder alternativ einem vergleichbaren Erdungssystem, das gemäß der geltenden Vorschriften genehmigt ist.

Do not connect the primary AC power earth ground wire to this lug. ACC2 provides safety ground connection inside the transformer wiring compartment.

 

4Slide Locks

The upper and lower slide locks secure the output modules in place. When they are open, power is off to the facepack, and an orange indicator is shown. The controller will not operate if a slide lock is open, and the status LED will flash orange to indicate this condition.

 

5Flow Expansion

A2C-F3 flow expansion modules add 3 additional flow inputs to the controller. These modules may only be added to the lower right module slot, one per controller, and it is the only module that will fit in this slot. The flow expansion module has DC voltage and polarity, and the + or red connection from the flow sensor must be connected correctly to the + (positive) terminals on the module. Finish flow expansion in the Devices, Flow Sensors menu after installing the module.

 

6Wire Tie Holders

Wire tie holders are molded into the lower back of the wiring compartment to secure field wiring with plastic “zip” ties. This provides a strain relief to keep field wires from pulling downward on the modules, and keeps the inside neat and organized.

Zusätzliche Drahtbinderhalter finden Sie bei der Netzteilplatine für Sensor- und weitere Verbindungen.

 

7Transformer Fuse

The transformer uses a replaceable 5 x 20 mm electrical fuse, located next to the convenient on/off switch. Two spare fuses are stored in the bottom rear of the facepack frame.

Diese Ersatzsicherungen sollten einen Glaskörper von 5 x 20 mm mit 250V und einer flinken 2A Sicherung haben, die Sie in jedem Elektronikgeschäft kaufen können.

 

8Optional Wi-Fi or LAN

Der Steckplatz für Wi-Fi oder LAN erlaubt die Installation optionaler Kommunikationsmodule.
