System 2 Installation / Programming Manual
If There is a Problem
If there is a problem with the board powering up, take the voltage measurements found in Figure 5. If there is
a problem with the programing read Chapter 8 or Chapter 9 “Programing” and try again.
If Everything tests OK
If the System 2 is OK then you need to decide when and where you are going to program the System 2. If
possible, programing it on the bench is easier. The System 2 has a Lithium battery for backing up user
memory. The System 2 can have its external power removed and retain its programming.
The lithium battery comes from the factory disconnected. Before you start programing, install the jumper that
is on pin 1 of H4 across pins 1 and 2. Once the lithium battery is connected to the System 2, disconnecting it
from ac power and standby battery should be kept to a minimum. Depending on the configuration of the
memory, the lithium battery should keep the Systems memory backed up for over a month but it can not be
recharged so unnecessary discharging could cause a problem later in the life of the System 2.
If you chose not to program until after the System 2 is installed, you can keep the test code programming by
connecting the lithium battery. This way, if there is a problem you know its not a programing error. It is
probably a wiring error.
Before starting the user programming, clear the memory. Go into program mode - Press x12345#. The main
menu should come up. Go into Option #17 - Press 17#. The prompt Are You Sure will display. Enter yes -
Press 1#. This will reinitialize the system and make you reenter the initialization setup. Before you enter this
setup again be sure this information is correct. To change this setup you must clear memory and all
programming will be lost. The information that the setup needs is the number of events to be stored, the
number of temporary users, user names yes or no, and networking yes or no. This information also determines
the maximum number of users, see Appendix A.
