Operating Instructions SWTD-1000 DYNALCO
1. Safety Instructions
SWTD-1000 may only be connected by trained & compete nt per so n ne l.
Before opening the SWTD-1000 (Hardware configuration) the unit must be disconnected
from circuits that may exhibit dangerous potentials.
The instructions in this operating guide m ust be strictly adhered to. Not doin g so may cause harm to
personnel, equipment or plant.
Instruments in a doubtful condition after electrical, climatic or mechanical overload must be immediately
disconnected and returned to the manufacturer for repair.
2. Product Features
The SWTD-1000 measures and monitor fr equencies (speed proportional values) in the range
0 to 35,000 Hz.
The following are available:
• 1 Current output
• 1 Sensor frequency output
• 1 Relay
• 2 Limits
• 2 Parameter sets – selectable via binary input
• Sensor monitoring
• System monitoring
This product is configured via SWTD-1000 PC configuration software.
All settings are in revolutions per minute (RPM).
