4 Operation

4.1 Overview

The DSPP is integrated into ECW utilizing a FIS terminal. Valve pitch is controlled by inputs from the

ECW-FIS sent to the logic program loaded on the motor controller. This section covers the following

topics:

•

Theory of Operation

•

Production Setup

4.2 Safety First

Operation of the Dual-Simultaneous Programmable Pitch involves mechanical devices and electrical

power. It is essential that every person servicing or operating the DSPP fully understands all hazards,

risks, and safety precautions. See Section 2 - Safety for additional information.

WARNING!

Allow only qualified personnel to perform the following tasks. Follow the safety

instructions in this document and all other related documentation.

4.3 Tools and Materials Needed

• Conformal Coating Characterization Card

4.4 Theory of Operation

The Dual-Simultaneous Programmable Pitch (DSPP) is a programmable valve pitch system that can be

mounted onto the Select Coat SL-1040 Conformal Coating System. The DSPP allows two of the same

conformal coating applicators to be installed and operated simultaneously, coating two parts at the same

time. The pitch, or distance between applicators, is programmed and adjusts automatically at

changeover, greatly reducing the setup time due to adjustments and validation. The DSPP provides valve

pitch adjustment from 55-205 mm. Minimum pitch can be increased to 100 or 130 mm when required to

prevent applicators from crashing.

4.5 Production Setup

4.5.1 Setup Travel Limits

Travel limits should only need to be setup once before the system’s initial production run. However, if

applicators are changed, if programs change, or if other hardware changes are made, travel limits may

need to be reestablished.

To setup travel limits:

1. Access the EasyCoat folder in File Explorer and search for file SNXXXXX.acl and open the

file in Notepad (Figure 4-1).

Figure 4-1 Open SNXXXXX.acl File

2. In the SNXXXXX.acl file, locate PE25 under TRAVEL LIMITS (X, Y, AND Z) (Figure 4-2).

Figure 4-2 Locate PE25

Dual-Simultaneous Programmable Pitch Owner’s Manual Operation

3. Subtract 2,000 from the PE25 value and change PE25 to the new value (Figure 4-3).

Example: 50582-2000=48582

Figure 4-3 Change PE25

4. Close and save the SNXXXXX.acl file (Figure 4-4).

5. Open RunACL and change the Com Port setting to COM1 (Figure 4-5).
