TIMER SETUP MENU: Remote Triggering Option
The PUF+ timer also supports timer events triggered via a remote device. In order to use this
feature, the unit must be configured to switch the timer into remote trigger mode and the
optional remote trigger cable must be used.
Use the SETUP>CONFIGURE>TIMER MODE menu item to set the timer mode to
REMOTE for remote triggering. For more details see the CONFIGURATION section of this
manual.
The remote trigger cable is available in two different styles depending on how the remote
device operates.
o
Style 1: Opto Isolated Connection – This is the recommend method of connection,
because it electrically isolates the remote device. This style connection requires a
+5V switch signal with a current capacity of 30 mA. This style cable can also be
used with contact closure type remote devices where remote power is available.
o
Style 2: Contact Closure Connection using Internal Power – This style is not
recommended, because of the possible increased risk of the remote signals causing
interference with the electronics. If this connection style is used, care should be taken
to insure that the system is wired to not interfere with the with the PUF+ controller.
It is also recommended to locate the contact closure as close as possible to the PUF+
Controller.
When in remote mode the timer has two different methods of operation.
o
Method 1: Duration Timed Mode – If the duration is set to a value other than 0, then
the timer will execute a timer event that starts when the remote signal is received and
last for the set duration.
o
Method 2: Remote Timed Mode – If the duration is set to a value of 0, then all timing
is dependent on remote trigger signal. When the signal is active the unit will activate
and operate as long as the signal is active.

In either mode, the unit records data just like timer mode events. Also, the remote timer
mode is automatically repeating as is relies on the remote trigger on when to start.
