G RELAY CONTACTS The relay contacts are rated for AC or DC operation Maximum recommended voltage 30 Volts Each relay has a set of potential free contacts There is no polarity to the terminals it is a normally open contact that closes in alarm condition These contacts are internally suppressed for EMI RFI and High Voltage transients resulting from inductive loads The relays may be programmed as fail safe which means they are energized in the off condition This way if the power should fail the relays will open into the alarm condition See note below 2 3 4 Digital Input The digital input is optically isolated and is activated by an external dc supply of 5 to 12Vdc at 20mA The input is via the DIGITAL INPUT and terminals The connection is the COMMON for the external input while the is the input for the positive voltage The digital input may be used as an External Trigger to stop or start recording or may be used to change the sampling speed Thus the unit can be set to record only when a conveyor is running for example The External Trigger may also be linked internally to the optional Relay Output This could be used as a remote record active indicator Refer to Sections on Relay setup and External Input setup Note In order to fully comply with the CE EMC Directive 89 336 EEC cables to the relay output and digital input should be looped through a ferrite Type Steward 28R2025 0R0 or similar close to the ter

68. t The balance of this introduction will attempt to introduce some of the more unique features of this paperless recorder 1 1 CHART SPEED TO SAMPLE SPEED A major difference between paper and paperless is SAMPLE SPEED which is analogous to CHART SPEED in the paper recorder There is an apparent chart speed the rate at which the samples appear to move across the Graphics Display but unlike paper recorders the display is made up of discrete data points each of which is a distinct sample of the data being measured The rate of movement across the screen is thus a direct function of the sample rate The major factor in deciding what sample rate to select is to know how much data is enough In a paper recorder a chart speed of 1 inch per hour is fine for a process that does not vary very quickly but would result in a thick blur if trying to record a 1Hz sine wave Unlike a paper recorder every point recorded by the paperless recorder is uniquely identifiable no matter how dense it appears on the screen It is always better to have too much data than to have too little The only consideration is the amount of space used in the memory card To relate chart speed to sample rate we need to consider how we plan to reproduce the data The graphic LCD display has a density of 70 pixels data points per inch a typical dot matrix printer has 180 pixels per inch and a laser printer 300 pixels per inch Thus to fill one inch of the display in one hour we ne
