control
Each of the four analog outputs of the FMS-2000C controller can be configured for the following operating modes:
• Direct operating mode
• PID operating mode
In direct operating mode, the output tracks the mapped analog input directly or inversely. The PID operating mode may or may not
employ the proportional-integral-derivative scheme for closed-loop control of the analog output. The range of the output can or cannot
include an offset. This is independent of the mode the analog output is configured to.
To change the operating mode, complete the following steps:
1. On the home screen, tap the
Settings
icon to enter the
Settings
menu.
