3.3.1.1 Sys Info - Page 1
This page is the system information page of the Sys Info menu. This page shows the
status of both power supplies PS1 and PS2. The controller monitors the output voltage
of each internal power supply. The power supply voltage is considered “Normal” if its
output voltage level is above 23V and “Fault” when output voltage drops below 22V. A
power supply fault is always considered a major fault.
Also included on page one of Sys Info is the System status. This is the status of the
system summary alarm. The system status will be “Fault” or “Normal” according to the
state of the various fault monitoring circuitry.
Aux is the state of the auxiliary fault input. Auxiliary faults are user configurable.
Depending on the system configuration they may be enabled or disabled and track
opposite logic states. When auxiliary faults are enabled, they will always trigger a
summary fault.
SW1 and SW2 are the position and fault state indicator of the transfer switch / switches
in the system. The possible states are: POS1 - Switch position 1, POS2 - Switch position
2, and Fault. In a system using only one transfer switch SW2 will be displayed as N/A,
not available.
Note on Switch Fault:
If the controller cannot read the position indicator lines on the transfer
switch it will be considered to be in a fault condition. This can occur when a
transfer switch becomes stuck between valid positions. The Summary fault
state may or may not be triggered depending on the user settings. The
system default is to consider a switch fault as a minor fault and will not
trigger a summary alarm.
3.3.1.2 Sys Info - Page 2
This page of the Sys Info menu pertains to the internal monitor and control settings of
the RCP controller.
Prtcl is the serial communication protocol settings. The possible settings are:
Auto - Auto detect either Standard or Locus Communications protocol
Standard - Standard extended protocol
Baud is the serial communication Baud rate selection. The available Baud rates include:
2400, 4800, 9600, 19200, and 38400.
Interfc is the physical interface used for serial communication. The available interfaces
include RS-232 and RS-485.
