1606-XL Redundancy Capabilities
The 1606-XL family has two cost effective methods for providing redundancy to applications that are critical and can not risk failure.
1606-XL60DR, XL120DR and XL240DR Redundant Power Supplies
The 1606-XL60DR, XL120DR and XL240DR are enhanced versions of the standard power supplies.
- Each device has internal diodes which provide isolation against DC bus problems corrupting working supplies.
- Provides "DC OK" output relay to allow remote monitoring of DC power status.
- Utilizes pluggable terminals for easy installation.
1606-XLRED20-30 and 1606-XLRED40 Redundancy Modules
Extensive Diagnostic & Monitoring Functions
- Wrong battery voltage (24V instead of 12V)
- Deep discharge (battery) protection
- Wrong battery polarity
- Wrong polarity on input terminals
- Too high ambient temperature
- Over-voltage protection
(malfunctioning of the internal regulation loops)
- Output overload or output short-circuit
A - Status LED (green):
- Ready: Battery is charged > 85%, no wiring failure is recognized, input voltage is sufficient and inhibit signal is not active.
- Charging: Battery is charging and battery capacity is below 85%.
- Buffering: Unit is in buffer mode.
B - Diagnosis LED (yellow):
- Overload: Output has switched off, due to long overload in buffer mode or due to high temperatures.
- Replace battery: Indicates a battery which failed the battery quality test (SCH test). Battery should be replaced soon.
- Buffer time expired: Output has switched off due to settings of buffer time. The signal will be stored and displayed for 15 minutes.
- Inhibit active: Indicates that buffering is disabled due to an active inhibit signal.
C - Check wiring LED (red):
- Check wiring between DC UPS and battery, as well as the battery itself. Also indicates when input voltage is not in range.
D - Adjustor:
- Buffer time limiter: User accessible switch which limits the maximum buffer time in a buffer event, to save battery capacity.
- End-of-charge voltage: User accessible potentiometer which sets the end-of-charge voltage. Adjust the potentiometer according to the expected battery temperature.
E - Signal contacts:
Ready (contact 1-2):
Contact is closed when battery is charged more than 85%, no wiring failure is recognized, input voltage is sufficient, and inhibit signal is not active.
Buffering (contact 3-4):
Contact is closed when unit is buffering.
Replace battery (contact 5-6):
Contact is closed when input voltage is sufficient and battery quality test (SCH test) indicates a negative result, three times in a row.
Inhibit input (contact 7&8):
The inhibit input disables buffering. In normal mode, a static signal is required. In buffer mode, a pulse with a minimum length of 250 ms is required to stop buffering. The inhibit is stored and can be reset by cycling the input voltage.
