Display Modes:
There are three modes of display: the Status Display Mode, the Program Mode, and the Fault Mode.
Status Display Mode
(Default Display)
The Status Display Mode displays seven “screens” of information. Motor Currents (3 phases), Remaining
Thermal Capacity, Ground Current, Remaining Time on the Process Timer, and Time Base of the Time Clock
Controller. This is also the entry screen for going into the Program Mode.
[0000.]
The initial display on power up is four digits and the decimal. This indicates the motor current for
Phase A of the motor.
[0000]
Scroll UP to display four digits only (no decimal). This indicates the motor current for Phase B. While
viewing Phase B, press the UP arrow again to view Phase C current.
[G000]
Scroll UP to display the “G”. This indicates that this value is the current flowing to ground on the motor
leads.
[H000]
Scroll UP to display the “H”. This indicates that this value is the remaining thermal capacity percentage
of the motor (i.e. H070 = 70% remaining thermal capacity)
[0000]
Scroll UP again to display the Process Batch Timer (described in Section 5.6.7). If this entire screen is
flashing, the Timer is active.
[00.00]
Scroll UP to display two pairs of digits separated by a point: This indicates the time base of the Time
Clock Controller (described in section 5.6.7 of the Advanced Installation, Operation and Programming
Manual). If the display shows [00.00], the TCC is not enabled. This follows the time settings in F075 – F080.
Program Mode
The starter must be OFF in order to enter the Program Mode. Changes cannot be made while running.
Use the Program Mode to view or change Function (Fn) settings. To enter the Program Mode, press the
[Fn]
key once from the Status Screen as described above. The first time you enter the Program Mode after power
has been cycled to the starter, the initial function
[F001]
should display with the selected digit flashing. If the
VMX Series
starter has been programmed and power to the unit has not been cycled, the readout will display
the last function viewed or changed. To change to a different function, use the arrow keys.
Viewing Function Programming and Values
The programming of each individual Function can be viewed without making changes (values can also be
viewed in the Run Mode, however no changes can be made). Each Function is signified by the letter “F” in
beginning of the data, the 4 digit value of the function follows after hitting the
[READ/ENTER]
key
[F001]
The “F” indicates the programmable Function.
[0000]
This is the present setting of the applicable function. This display may include decimals between digits
depending on the function setting’s range and incremental steps.
Pressing the [Fn] key
again will return to the Function display without making changes.
Changing a Function’s Set Value
From the instructions above, after hitting the
[READ/ENTER]
key the display will show the value of that function
with one digit flashing (usually the rightmost digit). Flashing indicates this is the digit to be altered (similar to
cursor position). Use the UP arrow key to increment the value of the flashing digit. Use the DOWN arrow key to
decrement the value of the flashing digit. Use the LEFT or RIGHT arrow to select the next digit to be altered.
Values can only be changed within the Adjustment Range of the function parameter.
Pressing the [READ/ENTER] key
again will store the new programming for that Function and return to the
Function display.
If the display shows [Inh]
when trying to store the changes, the unit is running and must be Stopped, or a
Password has been set up to prevent access and must be entered first. See section 5.6.12 of the Advanced
Installation, Operation and Programming Manual for details about this feature.
Caution! If the Fn key is pressed or power is lost before the [READ/ENTER] key is pressed,
the VMX Series Starter will not store the new value in memory.
