    The shelf has connections for AC inputs, DC output, and various alarm/control relays. The Pathfinder rectifier system is designed to operate with the Argus SM series of system control panels via RS-485 shelf connectors for communications. This allows the user to setup, control and monitor the entire power system and ancillary components from one central, easy-to-use source.

    ONTROLS Shelf Features The Pathfinder’s shelf contains connections for up to four rectifier power modules, AC input, DC output, sev- eral remote alarm/controls, and RS-485 communications. When the power modules are removed from the shelf, all cabling connections to the shelf are front-accessible with exception of DC outputs. DC connections are made at the rear of the shelf.
  • Page 16 W & 2 RGUS ECHNOLOGIES ATHFINDER 2.1.2 Shelf Alarms The rectifier shelf has alarms entitled RECTIFIER MAJOR, RECTIFIER MINOR, GENERAL ALARM, and AC FAIL. All alarms are “real time” and therefore do not latch. The minor and major alarm contacts are “fail safe”...

    The LED indicators provide visual indication of module operational status and alarms. The indicators and as- sociated colors are as follows: 2.2.1.1 AC Mains OK This indicator illuminates when AC input to the Pathfinder is within the valid range and flashes when out of the normal range (described below). 2.2.1.2 Flashing AC Mains OK The AC Mains OK LED will flash when the input voltage is out of range, but the module will continue to op- erate down to 90VAC (current limit gradually reduces automatically to approx.
  • Page 18 (and releasing) causes the module to shutdown and then restart immediately — the Pathfinder interprets this as a remote signal to turn the module on. To get a reading of output current, quickly press and release the power button. The lower green LED will flash for every 20% (approx.) of maximum rated output current.
  • Page 19 W & 2 RGUS ECHNOLOGIES ATHFINDER 2.2.5 True Module Fail Alarm The power modules have a “true” fail alarm. This provides a true indication of the power module's ability to source current. When the module's output current drops below 2.5% of the rated output, the Module Fail de- tection circuit is activated.
  • Page 20 2.2.18 Security Access Codes An adjustable three-digit security code is programmed into the Pathfinder modules to prevent access to criti- cal control functions by unauthorized users.

  • Page 21: Module Fail Alarms

    W & 2 RGUS ECHNOLOGIES ATHFINDER Module Fail Alarms The alarm conditions listed under this section signify a complete failure or shutdown of the module. 2.3.1 Remote Shutdown A module will turn off and extend an alarm when it receives a remote shutdown signal. 2.3.2 Output Fuse Open This alarm indicates the module’s output fuse has blown.
  • Page 22 This alarm is generated when the fan is sending an incorrect speed signal e.g. from excessive fan bearing wear. This alarm provides a warning that the fan may need to be replaced. The Pathfinder module will con- tinue to run normally during this condition.

  • Page 31 This function allows the user to adjust the slope percentage. Output slope is a method of load sharing which operates by altering the output voltage regulation of the Pathfinder module. Output slope is factory default at 1% and it is recommended to leave it at that value. Slope settings must be the same for all rectifiers in that system and should be 1%.
  • Page 32 The Module Fail LED will turn on and the Module Fail Relay will de-energize. The O/P HV SHUTDOWN and MODULE FAIL alarms will be extended remotely. The over voltage shutdown feature of the Pathfinder is selective and operates at 5% higher voltage in a less than 2.5% load condition.

    ATHFINDER EMOTE OMMUNICATIONS The Pathfinder rectifier system is optimized for remote communications. It can be controlled, monitored and tested via the SM series intelligent supervisory panel or via an ASCII display terminal. Multiple Shelf Connections (RS-485) Rectifier shelves can be daisy-chained together via the RS-485 interface. Refer to the customer connection drawings 030-633-08 for locations and pinout details of the serial communications interface (SCI) connectors.

  • Page 37: Communications Using A Pc/Terminal

    Before connecting the host equipment, ensure the communications access parameters – including default baud rate of your terminal – is set to match the Pathfinder module. The default parameters are set to 8 data bits, 1 stop bit, and no parity.

  • Page 38: Maintenance And Service

    Refer to the Specifications section at the front of this manual for replacement parts. Maintenance Although very little maintenance is required with Argus rectifier systems, routine checks and adjustments are recommended to ensure optimum performance. Repairs should be done by qualified service personnel.
