CHAPTER 3 - INSTALLATION GUIDE
R
efer to the appropriate wiring diagram during installation of
the 815UHP/H system. The wiring diagrams are in chapter 4.
1. Pick a spot for the 815UHP/H to be mounted. It is normally
mounted on the trailer. Do not mount the controller where
it can be damaged and it should be easy to see and out of
direct road spray. It is recommended that the controller be
mounted close to the pump control.
2. Mount the display enclosure using the mounting flange holes,
being certain to shim the enclosure away from the mounting
surface with the spacers provided to allow water drainage.
Broken display enclosures caused by water freezing
behind the enclosure are NOT covered by warranty.
IMPORTANT: When connecting wiring, all connections should
be soldered or securely connected using crimp connectors.
Do not use spade connectors as these will degrade over time.
3. Connect the wiring in accordance with the applicable wiring
diagram supplied by Garnet. The following chapter contains
a few typical wiring diagrams.
4. Use cable such as 7 conductor Scully cable or similar. Use a
strain relief where the cable enters the enclosure to create a
weatherproof seal. To simplify the wiring, use a junction box
available from Garnet. In addition, components such as cable,
strain reliefs, horns, hydraulic solenoids, etc. are available
directly from Garnet.
5. Program the alarm points in the gauge. Program alarm #1
as SHUT DOWN at the point beyond which loading is not
permitted. Program alarm #2 as SHUT DOWN at the point
where the horn alarm should activate. Program alarm #3 as
SHUT DOWN at the point where the tank is considered empty,
normally a few inches off the bottom. Do not program the
empty point right at the bottom, since any buildup of debris on
the anchor will prevent the system from clearing the bypasses.
Program alarm #4 as SHUT DOWN just above alarm #1. See
the 808P2 or 810PS2 manuals for programming details.
Example: The tank is 58 inches high, with a bottom reading of
4.6 inches. Suggested points would be alarm #1 (shutdown)
at 55 inches, alarm #2 (horn) at 53 inches, alarm #3 (reset) at
6 inches, and alarm #4 at 56 inches.
WARNING: To properly determine the shutdown point, raise
