PTE-300-V
Sheet 26
3.4.1.4. SYNCHRONIZATION
This key controls the different references available in the PTE-300-V. Each time this key
is pressed a different reference is selected.
3.4.1.5. MASTER/SLAVE control
Through this press key it is possible to select the available control modes when PTE-
300-V is interconnected with another PTE unit (BUS PTE).
There are two function modes:
•
Pressing normal: each time this key is pressed the mode will change to one of the following:
−
Independent
..
−
MASTER of reference
: PTE-300-V becomes the synchronizing reference for the
connected equipment. The phase angles we select in that equipment will be refereed
to the 0º phase angle in PTE-300-V.
−
SLAVE of reference
: the connected equipment becomes the synchronizing
reference for PTE-300-V. The phase angles we select PTE-300-V will be refereed to
the 0º phase angle in the connected equipment.
•
Pressing long: pressing for more than 2 seconds, the MASTER of control mode is selected.
This allows the control of the outputs ON/OFF and
Step to 2
nd
Value
for all the channels,
voltage and current, when interconnected with a PTE-50-CET.
3.4.2. OPTIC INDICATORS
3.4.2.1. RS-232 port indicator
This is a 3 mm LED (red). When it lit, indicates that the serial port RS-232 is active so
it can send or receive information.
3.4.2.2. SYNCHRONIZING REFERENCE indicators
They are three, 3 mm red LEDs. Only one is on at the same time.
•
Freq
: the internal generator generates the reference.
