5.0 NORMAL, AUTOMATIC OPERATING MODE
The operation mode setting is the master mode setting of the PEL-4. It controls whether
the PEL-4 is operational or in storage mode and how the PEL-4 responds to detected fault
conditions.
There are two normal, automatic operation modes:
 Fail-safe, in which the PEL-4 will operate automatically and will turn off if it detects
an internal fault, or;
 Best-effort (this is the default), in which the PEL-4 will operate automatically and will
attempt to continue operating if it detects an internal fault.
When the PEL-4 detects an internal fault, it will always set the alarm output, irrespective of
whether it is set to fail-safe or best-effort modes. In best-effort mode, in some fault cases it
will not be possible for the PEL-4 to continue operating. (For example, if the input voltage
drops below the low battery threshold then the PEL-4 will turn off and signal an alarm,
even if its operation mode was Best-effort mode.)
To set the Operation Mode, follow this sequence:
Operation =Program (or read) = 1 (or 9)
Feature =Operation Mode = 5
Value =XXX
The normal operation mode values are shown in bold in the following table:

Description
001 Normal Mode – fail-safe PEL-4 shuts down on fault
condition.
002 Normal Mode – best-effort
(default)
PEL-4 attempts to continue on fault
condition.
Other operation modes are available, for example, for remote control via hardwire input or
serial command. These are described in the more advanced sections of this manual and
listed in Appendix A.
The PEL-4 can be programmed over the serial interface of the Dataport. Appendix A
includes references to the serial interface commands that are equivalent to, or associated
with, the TVIR programmer commands. A detailed description of the serial interface
commands is provided in Appendix H.
The following sections describe programmable features and parameters that are
supported in normal, automatic mode.
5.1 Flash Character
Vega PEL-4s are pre-programmed with 246 standard characters, each represented by a
three digit code (XYY). The first digit of the code represents a flash type – such as 1YY for
Isophase characters. If additional flash characters are required that are not included in the
standard set, these can be included if advised at time of order. These would then be
available for programming under User Character Type 9YY.
