Power On
When power is first applied to the controller, both displays
and all LED indicators are momentarily illuminated. The
Process Value (PV) window then displays [ -At- ] or [ -Ap- ]
and the Setpoint Value (SV) window displays an initialization
code, e.g., [ tf05 ]. The last two digits of this code indicate the
software revision supplied with your controller. Please pro-
vide this revision number when contacting us regarding your
controller. Depending upon whether Setpoint Target Time
[SP.tt] is enabled, you may also see this symbol: or
. This means that the controller is ramping
up or down to setpoint according to its previously pro-
grammed parameters. The default setpoint on initial power up
is equal to the process temperature (process value). Before
proceeding
further, wait until the display has stabilized and then use the
Raise or Lower keys to enter or adjust your
desired Setpoint Value.
