SETTINGS SCREEN VIEWING/EDITING SETTINGS
SETTINGS SCREENS
To enter the settings sequence press the ENTER
pushbutton while in the Settings screen. This will take
you to the settings sequence, where you can view or
edit system parameter settings. These screens follow the
sequence shown in Figure 10; pressing the UP or DOWN
pushbuttons 10 times returns you to your starting position.
Each screen has a line at the top which describes the
parameter or group of parameters. Press the ENTER
pushbutton to edit the parameter or group of parameters.
If the Panel Lockout feature is turned on you will see a
screen that says “Edit Function Locked Out”. The BACK
pushbutton will take you back to the default screen.
All settings are stored in the unit’s non-volatile memory,
this means that the PT-SINGLE will retain the settings
entered even if the unit loses or is disconnected from the
power source. Holding the UP and DOWN pushbuttons
together for ve seconds in the settings screen will restore
all settings to their factory default value, if desired.
Basic Editing of Settings
When on the desired screen press the ENTER pushbutton
to edit the values. Use the UP and DOWN pushbuttonsto
change the parameter values, press the buttons quickly to
change the number values decimally, or hold thebuttons
to scroll through the number values more quickly. The
ENTER pushbutton saves the value setting. The BACK
pushbutton cancels the edit operation if not saved and
returns to the original value at the start of the edit.
Multi-eld Screen Editing
In screens that display multiple elds, there are two
columns. The left column displays the name of the
parameter, and the right column displays the current
value. Initially, one of the elds in the left column will be
selected (have a selection box around it). Use the UP and
DOWN pushbuttons to change the row which is selected.
Press the ENTER pushbutton to edit the parameter in
that row, the selection box will move to the right column,
indicating that an edit operation is in process. After you
are done editing, press the ENTER pushbutton to save the
new value, or the BACK pushbutton to make no change.
The selection box will move back to the left column.
Alarm Options Screen Editing
The “Alarm Options” screen has three binary (on/off)
conguration settings:
Latching: this controls whether non-critical alarms latch.
When ON, alarms need to be cleared manually by using
the red key. When OFF, the alarm will go away when the
alarm condition resolved. The default for the Latching
setting is OFF.
Fail Mode: this is a safe state setting which can be set to
energize or de-energize the heaters if the sensor fails. The
default setting for the Fail Mode is ON.
Fire Prot: this controls whether the Fire Protection mode is
active. When ON, a ground fault or over–current alarm will
not inhibit operation of the heater. When OFF, a ground
fault or over–current alarm will de-energize the heater.
The default setting for the Fire Protection mode is OFF.
When in the edit mode the description and meaning
of the currently selected parameter is displayed at the
bottom. As you edit the value, the description will change
accordingly.
Note: To restore all settings to factory default press
both the UP and DOWN pushbuttons together for
ve seconds while in the settings screen. The unit will
prompt the user for acknowledgement before changing
the settings.
