PD6928 Ex-Proof & I.S. Loop-Powered Flow Rate/Totalizer
Instruction Manual
49
Sample (
SAMPLE
)
A relay set to sample will trigger when the total or grand total value has incremented by a programmed amount.
The relay can be programmed to stay on for a specified amount of time.
For example:
if a relay is set to sample the total with a
COUNT
of 1,000 and a
TIME
of 10 seconds, the relay will
engage for 10 seconds whenever the total has incremented by 1,000 (e.g. 1000, 2000, 3000).
Timer (
TIMER
)
The timer output may be set to generate the timed pulse only once (
ONESHOT
) or continuously (
CONT
). The timer
output produces a constant width pulse at a constant frequency, if set as continuous timer.
Program the
Off Delay
(
OFF.DLAY
) from 1 second to 99 hours 59 minutes and 59 seconds. This is the time it takes
from selecting
START
to turning on the output and for how long the output is off in continuous mode.
Program the
On Time
(
ONTIME
) for the active low pulse from 1 second to 99 hours 59 minutes and 59 seconds
(pulse width). This is the period of time for which the output will remain on.
Select
Start
(
START
) to begin outputting the constant timed pulse. Select
Stop
(
STOP
) to end outputting the constant
timed pulse. Function keys or the digital input may be assigned to start and stop timer functions (see the
USER
menu
in
Advanced
).
