Installation
TB-50 Connections
4 and 8 CLS TB-50 Connections.
If you install a Watlow Anafaze Serial Digital to Analog Converter
(SDAC), the CLS uses digital output #34 for a clock line. You cannot
use output #34 for anything else when you have an SDAC installed.
* The indicated outputs are dedicated to PID (or control) when enabled
in the loop setup. If one or both of a loop’s outputs are disabled, the
corresponding digital outputs become available for alarms or ramp/soak
events.
