7.1.2
Remote Control
Start, Stop & Reset control via the digital inputs on the front of the Auxiliary Master Module (see Figure 11-3:
Customer Terminals for Remote Control and Monitoring of PCS100 AVC-20) is deemed "Remote Control."
Control

Stop
Reset
A Stop input has priority over any start command. When a Remote Stop is active "INHIBITED" will show on user
interface as shown above.
7.1.3
Start/Stop Configuration
The PCS100 AVC-20 is configured for GDM control by default in the factory, i.e. Stop/Reset/Inhibit input is linked
out and Stop-Enable switch is wired in series as shown on Figure 11-3: Customer Terminals for Remote Control
and Monitoring of PCS100 AVC-20
The start status will be retained through a power down cycle and the PCS100 AVC-20 will return to the previous
operation after the next power up.
7.2 Output Voltage Set Point
PCS100 AVC-20 provides the ability to adjust the output voltage and the output voltage reference source.
The output voltage reference source can be the GDM screen, an analogue input or Modbus. Parameters for
setting up the output voltage reference source can be found under Menu 6 References as shown in Figure
7-6 below.
For output voltage control via the GDM screen, parameter 601 V Set Source must be set to Manual, and the
voltage set point is adjusted via parameter 600 V Set Manual. For example, in Figure 7-6 the system is set to
manual control and 400 V output voltage.
In Manual control, any other reference is ignored and the parameters 602, 603 and 604 are not used.
Method
When the Start input closes (terminals 12 & 13) the PCS100 AVC-20 will
start (Online) in approx. 1 sec.
When the Stop/Reset input opens (terminals 14 & 16) the PCS100 AVC-20
will transition to stop (static bypass) in approx. 1sec. The stop always has
priority over the start.
When the Stop/Reset input transitions from open to close the PCS100
AVC-20 will reset when a fault condition exists if the cause of the fault
has been cleared.
