Key
Pressing the REM key causes the VersaPro to cycle between Remote, Automatic, or Manual control. This key
has no function in the monitor version. When switching from Automatic to Manual or Manual to Automatic, the
control output remains at the last output value in either mode. This allows for a bumpless control transition
between manual and automatic mode.
When the controller is set to Automatic mode the “Auto” LED lights and the lower display indicates the process
setpoint (default).
When the controller is set to Remote mode the “Rem” LED lights and the VersaPro will accept a remote
setpoint from a master on the host serial interface. The lower display indicates the process setpoint (default).
The Setpt key does not work if the instrument is in remote mode.
When the controller is set to Manual mode both the “Rem” and “Auto” LED’s will flash together and the lower
display indicates the power output of the controller. This value can be manually increased or decreased in 1%
steps by pressing the UP or DOWN arrow keys. Pressing the RIGHT or LEFT arrow keys changes the output
in 10% steps. The output will remain in the last control level if the instrument is switched into manual mode
from remote or automatic or back to either setpoint control mode.
