Timers
Six independent timers are provided in the
BE1-BPR. Each timer consists of a time delay
setting (TD[x]), a start input, a reset input, and an
output (T[x]). Timing starts when the start input is
true and the reset input is false. The timer runs
for the duration of the time delay setting unless
the reset input becomes true. When the time
delay expires, the output changes state. A timer
can be configured as a delay or control timer with
independent or dependent start and reset
conditions. Timers can be used to provide a
diagnostic log and/or alarm. Figure 4-6 illustrates
the timer circuit components.
The LT command is used to configure timers for control or delay operation and define the start and reset
logic.

LT Command
Purpose:
Read or change timer logic
Syntax:
LT[x][=<type>,<start>,<reset>]
Comments:
x = the number of the timer being read or changed (1, 2, 3, 4, 5, or 6)
An access area one password is required to change settings.
LT Command Example
Configure timer 1 as a delay timer that is started when contact input 1 is energized and stopped when output
6 is de-energized. Configure timer 2 as a control timer that is started when input 2 is energized and stopped
when input 2 is de-energized.
LT1=D,I1,/O6; LT2=C,I2,/I2
The TD command is used to read or enter the delay settings for each of the six timers.
