Test AC Power
Turn on main power. The enabled sensor values will display on the Run Screen after
the initial YSI splash screen. If applicable, install and configure DC power backup
page 45. Verify AC power at the Menus → System →Version menu - page 125.
See Power Fail Menu - page 117 for AC power event log information.
Wire DC Power and backup power
The 5200A may be powered by most 9.0-16.5 VDC source that provides 800mA of
current and is isolated from mains supply by double or reinforced insulation. The
DC power source is user-supplied and can come from a variety of choices including
lead acid, gel cell, or UPS (with 12VDC transformer) external batteries. DC power
wires are terminated at location B on the I/O Board - figure 3.18.
Notes:
The 5200A does not charge batteries. Quality assurance maintenance -
procedures should be established if batteries are to be fully powered when
used as back-up power source.
Power supply voltage above 16.5 VDC may permanently damage the -
5200A.
Installation and Wiring
When back up voltage falls below 9.0 volts, the 5200A ceases to operate -
properly.
Some switching DC power supplies not supplied by YSI may result in -
noisy readings.
Directions to Wire DC Power/DC Backup Power
WARNING: Disconnect external power to the unit before wiring. Follow
all manufacturer’s safety and installation instructions when providing power to
