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 (ON TIME) 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
the Advanced Menu).
Stopwatch (STPWATCH)
The stopwatch function may be used to manually run
and control a process for a specific time interval up to
99 hrs., 59 min, and 59 seconds. The stopwatch func-
tion may be assigned to any open collector. There are
three settings needed to use the function effectively.
1. Assign stopwatch to either top or bottom dis-
play line
2. Assign the open collector to control the pro-
cess (on/off)
3. Assign a function key or digital input to
start/stop the stopwatch
Application Example
In order to maintain consistency of a product, it is
necessary to take and test samples at different times
throughout the day. The stopwatch function is used to
open and close a solenoid valve to know the exact
amount of time needed to complete the desired sam-
ple. Once this is determined, the timer function can be
used to automatically take a sample (batch) based on
the time determined using the stopwatch function.
Setup: Assign the following to Stopwatch Function
• Bottom display line
(see pages 21 & 22 for details how to
change the display)
• Relay 1
(see pages 23 & 26 how to change Open Col-
lector and or Solid State Relay functionality)
• F3: Start/Stop
(see pages 34 & 35 for details on how to
change the function keys)
Procedure
• Press F3 to start the stopwatch; relay 1 turns
on and the process starts running.
• Press F3 to stop the stopwatch; relay 1 turns
off and the process stops.
• The bottom display indicates the time it took
to complete the sample.
