CL190/CL191 Lens Controller - User Manual
7.1.1
Trigger input options
You can connect the following types of trigger to the trigger input:
10V to 24V voltage source
Any voltage between 0V and 0.9V
is taken as logic 0.
Any voltage between 10V and
24V is taken as logic 1.
PNP signal
You can connect a PNP open
collector drive to the CL191's
input. Use the connections shown
opposite. The PNP transistor
should not pull up to more than
24V.
If the P flag is set to ‘1’ the CL191
trigger is on when the driving
transistor turns on. To reverse
this, set the P flag to ‘0’ (see
).
Analog signal
A 0V to 10V analog signal is input
to control the lens optical power
when the controller is in Analog
mode. This can be linear or non-
linear (see
).
7.2
Flags
You can set flags on the CL191 controller to alter its operation. They can
be set from the unit’s front panel, the webpage or through the
RE
command (see
Section 9 , Configuration commands
). The following
configuration flags are available:
E Flag
– Enables or disables fault detection. Error checking is enabled as
the default setting.
P Flag
– Sets the trigger input active high or active low. The default setting
is active high. Refer to
Section 7.1.1 , Trigger input options
for a detailed
description of the settings.
