1 Introduction This document is intended primarily as a reference for production operators of C-718, C-718-SMT, and C-718-SMA Dispensing Systems. However, others unfamiliar with Asymtek products may also find this document useful as a general introduction to the system. Refer to the Century Series C-718/C718-SMT Installation, Operations, and Maintenance Manual for detailed information. Century C-718 Series Dispensing Systems are designed to solve the diverse needs of the fluid dispensing market.
2 Safety Basic Safety Precautions • Only trained personnel should be permitted to perform operation, maintenance, and troubleshooting procedures. • Locate, identify, and obey all safety warning labels on your system before initial use. Refer to Safety Warning Labels in this section. • Immediately push the red Emergency Machine Off (EMO) button if personnel are in danger of being injured. Refer to Emergency Shutdown in this section. • Do not wear loose clothing or jewelry while operating the system.
Safety Warning Labels The symbols in Table 2-1 may be found on your dispensing system or accessories to warn personnel against potentially hazardous areas. Failure to heed a warning symbol could lead to personal injury and/or damage to equipment.
Emergency Shutdown Your Century C-718 Series Dispensing System features an Emergency Machine Off (EMO) button that the operator or service technician can use to immediately stop all dispensing operations in case of emergency. This feature helps prevent injury to personnel and damage to the dispensing system and workpieces being processed. The EMO button is located on the Control Panel on the front of the dispensing system (see Figure 2-1).
Safety Interlock Switch The Safety Interlock Switch is located on the Control Panel (see Section 3 Component Description ). It is designed to restrict access to the inside of the dispensing system, based on user-defined levels of operation. The Safety Interlock has two modes: ON (l) or OFF (0). Once an Interlock safety mode is selected, the key can be removed to prevent an inadvertent mode change. The Safety Interlock is designed to work with either the Door Sensors or with the Light Curtain.
Light Beacon The Light Beacon (Figure 2-3) is a device that displays system status whenever the dispensing system is ON. The Beacon has four colored lights that can be constantly ON or flashing and has an audible alarm. The colors on the Light Beacon correspond with the System Status LED’s on the Control Panel. Table 2-2 defines the colors.
Table 2-2 Panel / Beacon Colors, Dispensing Status and Recovery Procedures Panel / Beacon Color RED YELLOW GREEN Dispensing Status Recovery Procedures ALERT All motion, outputs, valve and motion controls are disabled. One of the following conditions exists: A. Doors open or light curtain is obstructed when system is moving, INTERLOCK at I. B. System is in an abort state. A or B: 1.

Pneumatic Regulator Adjustment Operators may have to adjust the air pressure when the dispensing valve or application changes, or to prepare the system for maintenance or servicing. Pressure settings will depend on the application. " NOTE When decreasing pressure, lower the pressure past the target level, then rotate the adjustment knob clockwise (right) to raise pressure to the desired setting. This will help prevent false readings.
