Direct Access to Setpoint Modification
When direct access to setpoint modification is required,
proceed as follow:
1. Push, for more than 3 seconds, the ▲ or ▼ pushbutton;
the set point value, shown on the lower display, will
start to change.
2. Using the ▲ and ▼ pushbuttons, set the desired value.
3. When the desired value is reached, do not push any
pushbutton for more than 3 seconds. The new setpoint
will become operative 3 seconds after the pushbutton is
released.
If, during this procedure, there is no interest in
memorizing the new value, push the FUNC pushbutton;
the controller returns automatically to the normal display
mode without having memorized the new setpoint.
Output Power OFF
To turn the output signal OFF, press and hold the ▲
pushbutton then push FUNC.
Pressing both pushbuttons for more than 3 seconds, will
cause the controller will show “OFF” instead of the set
point value.
In the output power OFF condition, the parameters can
always be viewed and modified. When control is disabled
(output power off), the alarms are not in an alarm
condition. The alarm output status depends on the type of
alarm action.
When the output is OFF, all parameters can be reviewed
and modified. The SMART function will be disabled
during the OFF condition. If power is lost, the unit will
power-up in the OFF condition.
To return to normal control, press and hold the ▲ and
then push FUNC for more than 3 seconds. The controller
then automatically goes to the NORMAL DISPLAY
MODE.
The alarm inhibit function, if configured, will be
activated as if it were a powerup.
Lamp Test
To verify operation of the display LED, push ▼ and
FUNC together. The instrument LEDs will flash until the
Lamp Test is turned off.
To turn off the Lamp Test, press ▼ and FUNC together.
No pushbutton functions are operable during the Lamp
Test.
