  • Page 7 210-NY RMS Signal Monitor Operations Manual Section 1 GENERAL DESCRIPTION INTRODUCTION This manual covers the operation, equipment usage, and design considerations of the 210-NY series Signal Monitor. It provides the user with a general understanding of the operating principles necessary to install and maintain the model 210-NY series Signal Monitor.
  • Page 8 210-NY RMS Signal Monitor Operations Manual are required. The indicator will remain illuminated to indicate a Watchdog fault existed but was cleared by the power loss. The WDT Latch option (see section 3.3.1) determines whether this WD FAULT or WD@LOW VOLT fault mode is latched through an AC Line brownout or not.
  • Page 9 210-NY RMS Signal Monitor Operations Manual Section 2 GENERAL CHARACTERISTICS The following extended features are provided on the 210-NY series Signal Monitor to provide additional fault monitoring functions, to increase the reliability of the monitor operation, and enhance the diagnostic capabilities offered to the service technician.
  • Page 10 210-NY RMS Signal Monitor Operations Manual Figure 2-1 shows an example of a recurrent Conflict fault. Channel 2 Green is detected active due to a malfunction of the load switch which caused the output to Aflicker@ On for 100 ms approximately every 200 ms. Since normal Conflict detection requires a continuous fault of at least 350 ms typical, this event could go undetected.
  • Page 11 210-NY RMS Signal Monitor Operations Manual This type of failure is configured as latching. With latching operation, only a loss of AC Line will restore operation. If the microprocessor resumes operation the unit will not return to normal operation. If non-latching operation is desired, jumper E5 may be removed.
  • Page 12 210-NY RMS Signal Monitor Operations Manual To enter this display mode remove the Program Card. Depressing the Reset button advances the display mode from the normal mode to the Green field input display. The (G) AC POWER LED will pulse ON once per second to indicate this mode.
  • Page 13 The 210-NY series Signal Monitor also provides jumper options to modify the monitor operation. The Select jumpers are labeled SEL1 through SEL10. SEL6 through SEL10 are reserved for EDI configuration programming and should not be modified except by the factory.
  • Page 14 210-NY RMS Signal Monitor Operations Manual 3.2.7 AC LINE BROWN-OUT SELECT (SEL5) When jumpered, the AC Line Brown-out levels will be set for the 2010 series with Adropout@ at 98 + _ 2 Vrms and Arestore@ at 103 + _ 2 Vrms with timing at 400 + _ 50 ms. When not jumpered, the AC Line Brown-out levels will be set for the 210-NY series with Adropout@ at 82 + _ 2 Vrms and Arestore@ at 88 + _ 2 Vrms with timing at 80 _ + 17 ms.
  • Page 15 210-NY RMS Signal Monitor Operations Manual Section 4 FRONT PANEL DESCRIPTION INDICATORS (G) AC POWER Indicator The AC POWER indicator will illuminate when the AC Line voltage level is above the brown-out "restore" level. The indicator will extinguish when the AC Line voltage is below the "drop-out" level. If the AC Line voltage is detected above 135 2 Vrms, the AC POWER indicator will flash at a 2 Hz rate.
  • Page 16 210-NY RMS Signal Monitor Operations Manual may be required. The Reset button also provides control of the Diagnostic Display mode. For a complete description of Diagnostic Display operation see Section 2.12. Eberle Design Inc. Page 10...
  • Page 17 210-NY RMS Signal Monitor Operations Manual Section 5 THEORY OF OPERATION SYSTEM DESCRIPTION The 210-NY series Signal Monitor uses a dual microprocessor architecture consisting of an MC68HC11D0 main microprocessor unit (MPU) and a Microchip PIC17C43 based RMS-Engine. The RMS-Engine is a dedicated single-chip high speed micro-controller used to sample the AC field inputs and calculate the true Root Mean Squared (RMS) voltage.

Under normal conditions the microprocessor will clock this circuit every 20 ms. If jumper E5 is installed this fault mode will only be reset by a complete power down cycle. 5.2.4 EEPROM MEMORY The 25C320 Serial EEprom (U20) device provides 4096 bytes of nonvolatile memory.
