PTE-50-CET
Sheet 18
This knob has no end and can be controlled at any speed. However if the control knob is
turned very fast the value will change at a maximum rate of 1 digit per second.
c) Output ON/OFF selection
When this key is pressed the output will turn on and the LED situated below
will light up.
When it is pressed again it will disconnect this output and the LED will be off.
d) 2
nd
value selection
When this key is pressed it allows the selection of a 2
nd
value and it is shown in
the display. This selection does not cancel the value already selected in the
output at the moment. To distinguish the actual value from the 2
nd
value
selected, the LED over the key lit when the 2
nd
value is displayed.
e) Activating 2
nd
value
This key works in a sequential way. When pressed the output value changes to
the 2
nd
value, when it is pressed again it will return to the 1
st
value.
When this key and the similar key in the phase section are pressed at the same time for
more than 2 seconds this function if both sections becomes synchronized. To cancel you
must repeat this process.
f) MASTER/SLAVE: regulation modes
The following press keys are installed on the PTE-50-CET
to achieve regulation capability in terms of three-phase
regulation, fault combinations, like a phase to phase,
three-phase, etc.
•
Output channel 1 (CH1): MASTER key.
•
Output channel 2 (CH2): SLAVE key.
•
Output channel 3 (CH2): SLAVE key.
When no key is activated, the output channels are completely independent in all their
functions.
When the MASTER key of CH1 is activated, at least one slave must be activated also. The
MASTER function affects all channels in SLAVE mode (CH1, CH2 or both) as follows:
•
Any output value change made in CH1, through the rotating knob in level or phase
angle, occurs immediately in the SLAVE channels.
•
If the output mode (voltage or current) is changed in CH1, it changes immediately in
the SLAVE channels.
