ON/OFF status of the system will be updated on speedDIAL when it is controlled via TTL.
However, due to the communication lag time between the main unit and speedDIAL, if
LED “on time” is less than 30ms, the change may not be displayed.
5.2.2
TTL Mode Timeout
There is a potential disadvantage of TTL mode - in this “always active” state, the system
continues to consume energy and mechanical components accumulate wear. To help minimize
unnecessary consumption at the end of an imaging session (or if equipment is accidentally left
on), this unit is equipped with a TTL timeout setting. The factory default for the TTL timeout
setting is “Never”, but defining a timeout is recommended for any imaging session that will end
without an operator present to shut down equipment (e.g. middle of the night).
