Site Master - Main Control in a Line of Controllers (Can Have up to 3 Slaves)

Site Master - main control in a line of controllers (can have up to 3 slaves)

·  Every time you ADD a controller to the network you need to reset the Site Master and you need to pull the blue jumper behind the RS485 COMM Port of the controller added.------

Troubleshooting Zones

You want to make sure the blue jumpers in the line of controllers are removed.

Make sure that the controllers are all assigned their proper network titles in programming.

Then Enable the COM DIAG SCREEN on Site Master.

·  You would have to enable this feature by doing the following

·  Menu>SystemSetup>AdvanceSettings> scroll down to Comm Diag Screen and enable show

·  hit +or- then hit back and completely exit out.

·  To see Controller Network - press “PREVIOUS” at the main status screen

·  This will display 4 double diget columns

o  On screen the zero by itself is the error counter

NOTE: errors could be high by previous episodes if it’s fluctuating considerably when you open the screen then there’s an issue

·  Site Master uses Local and slaves attached use Remote

·  Zone Master uses Local any slaves attached uses remote

·  Make sure your additional Zones or Slaves are not disabled

·  Check RS 485 Connections Wiring May Be Loose

·  Check and see the Blue Jumpers are pulled all except the last Controller

·  You may have to reposition the Main Module gently lifting and reseating it (make sure to power down controller prior)

o  Check to see if the Pins are not seated flush with the board

If PROGRAMMING CHANGES are made make sure you reset

·  Controller which changes were made

·  Site Master (SM) so he can auto detect the network changes.

S/M Communicating with Additional Controllers on the RS 485 Chain.

If the SM can’t see Zone Master or Slave attached and vice versa it could be a:

·  Wiring

·  Programming

·  Chip Issue

------

BYPASS TEST #1- making the following controller the SM

Make next controller in the line of controllers the Site Master (SM)

bypassing controller in question.

and then reset newly appointed Site Master (SM) and see if communications are established.

BYPASS TEST #2- making the controller in question OFF and allowing COMM TO FLOW THROUH IT.

Unplug the controller in question which will power down the communications of that controller but will allow the RS485 connections to continue on to the following controller

RS 485 wires screwed together - simulating wire nuts continuing the signal

INDEPENDENT TEST

What you want to do is the following test on each controller INDEPENDENTLY

Make the controller a site master (SM) as a stand alone,

·  Disconnect RS485 Wiring (no controllers attached)

·  Remove blue jumper

·  Enable the COMM DIAG SCREEN (You would have to enable this feature by doing the following) Menu>SystemSetup>AdvanceSettings> scroll down to Comm Diag Screen and enable show

·  hit +or- then hit back and completely exit out.

·  To see Controller Network - press “PREV” at the main status screen

·  This will display 4 double digit columns

o  On screen the zero by itself is the error counter.

If the zero is not moving, and is constant its ok

If the zero is moving and the error counter is increasing in #’s

Do the same test on the other controller in question. And please let me know of your findiings
