5. 1 0 GENERAL DESCRIPTION The Net Safety Monitoring Inc SafeGuard 16 channel Controller is designed to display and control alarm event switching for up to sixteen detectors Flame detectors or transmitters with gas sensor data points It may also be set as an eight channel SafeGuard Controller for applications needing fewer inputs Alarm features such as ON and OFF delays Alarm Acknowledge and a dedicated horn relay make the SafeGuard Controller well suited for many multi point monitoring applications Data may be input to the SafeGuard Controller by optional analog inputs or the standard Modbus RTU master RS 485 port A Modbus RTU slave RS 485 port is also standard for sending data to PC s PLC s DCS s or even other SafeGuard Controllers Options such as analog I O and discrete relays for each alarm are easily added to the addressable bus Option boards have 8 channels and therefore require 2 boards for 16 channel applications Note LEL Gas sensors are connected to the SafeGuard Controller via Net Safety Transmitters They are NOT connected directly to the SafeGuard Controller at this time Perform calibrations of the transmitter sensor head Calibrations may however be performed at the SafeGuard if the transmitter sensor configuration is in a location not easily accessible See Cal Mode A 240 x 128 pixel graphic LCD readout displays monitored data as bar graphs trends and engineering units System configuration is through use
6. 40 Appendix Appendix A Electrostatic Sensitive Device ESD Definition Electrostatic discharge ESD is the transfer between bodies of an electrostatic charge caused by direct contact or induced by an electrostatic field The most common cause of ESD is physical contact Touching an object can cause a discharge of electrostatic energy ESD If the charge is sufficient and occurs near electronic components it can damage or destroy those components In some cases damage is instantaneous and an immediate malfunction occurs However symptoms are not always immediate performance may be marginal or seemingly normal for an indefinite period of time followed by a sudden failure To eliminate potential ESD damage review the following guidelines e Handle boards by metal shields taking care not to touch electronic components e Wear grounded wrist or foot straps ESD shoes or heel grounders to dissipate unwanted static energy Prior to handling boards dispel any charge in your body or equipment e Ensure all components are transported and stored in static safe packaging e When returning boards carefully package in the original carton and static protective wrapping e Ensure ALL personnel are educated and trained in ESD Control Procedures In general exercise accepted and proven precautions normally observed when handling electrostatic sensitive devices A warning label is placed on the packaging identifying product using ele
