INTRODUCTION
The
Generator Controller provided monitoring and control of essential
function for a diesel generator set. Voltage free contact inputs
are monitored using low power and noise tolerant techniques. Relay
outputs are rated for 10 amps 240 volt AC or 30 volts DC. there
is one push button input for testing the LED indicators and to
reset any fault conditions.
SPECIFICATION
| Operating
voltage range: |
Low
voltage link installed - 6V to 24V
Low voltage link removed - 13V to 34V
|
| Quiescent
current: |
50mA
(one lED lit, all inputs open) |
| Maximum
current: |
1
amp (all relays and LEDs energised) |
| Temperature: |
0
to 70 deg.C |
| Humidity: |
10
to 90% non condensing |
| VF
Contact Inputs: |
Source
approx. 5V @ 100mA wetting current (multiplexed) to external
N/O voltage-free contacts. response time 1 second typical
after debouncing.
Response time becomes longer as duty ceycle becomes less than
100%. Duty cycle must be > 50% for response to input. |
| Tacho
Input: |
100mV
to 30 Volts P-P, adaptive. Input impedance > 20k ohm. Ring
gear teetch in range 100 to 220 accommodated. |
| Generator
Voltage Input: |
Senses
RMS generator voltage within +/1 2% over range 180 to 275V. |
| Outputs: |
N/O
voltage-free relay contacts rated 10A 240VAC, 30VDC (non-inductive)
