Mounting the Panel
1. Select a suitable mounting location on or near the engine. The location
should provide easy access to the panel and provide unobstructed
viewing of the Swichgage instruments.
2. The mounting location should avoid shock and vibration to the extent
possible. Generally, a location low on the engine is preferred. Avoid
m o u n t i n g o n t o p o f t h e e n g i n e i f p o s s i b l e . S h o c k m o u n t s a r e
suggested where possible to dampen shock and vibration.
IMPORTANT:
Use of improper shockmounts can accelerate the shock
and vibration effects. Consult the factory if you are in doubt.
NOTE:
If shockmounts are used, it is suggested that a separate ground
wire be attached to the panel assembly and to the engine. This assures
electrical continuity between the Swichgage contacts and the battery
ground across the shockmounts (see mounting detail below).
Connecting the Pressure Swichgage
1. Pressure tubing is generally not provided. Use of good quality flexi-
ble pressure tubing/hose and fittings is strongly suggested. Use at

tubing, install at least 12 in. (305 mm) flexible hose from the pres-
sure Swichgage instrument to the rigid tubing. This prevents damag-
ing vibration from reaching the Swichgage instrument.
2. Connect the pressure tubing to the

27 NPT pressure port of the
pressure Swichgage instrument. Use of a non-hardening thread seal-
ing compound is recommended although the thread is “dry seal”. Be
sure that thread sealant does not foul the pressure orifice.
NOTE:
The orifice can be removed for cleaning.
3. Connect the pressure tubing to the pressure galley of the engine.
Generally this is at the oil filter housing. Use of non-hardening
thread sealant is recommended. Avoid droops or sink traps in
routing of the pressure line.

INSTALLATION INFORMATION
Description
Generally, pressure and temperature Swichgage
®
contacts are wired to a
central nerve center called a Magnetic Switch or Tattletale
®
annunciator.
T h i s n e r v e c e n t e r i s e s s e n t i a l l y a r e l a y a n d , w h e n s i g n a l e d b y a
Swichgage contact operation, it either makes or breaks a circuit to oper-
ate an alarm or engine shutdown device. Various nerve centers are used
depending upon the operation to be performed, the type of electrical
power available and the type of alarm or shutdown device used.
Typical wiring diagrams for the popular Tattletale annunciators and magnet-
ic switches are included in this instructions. If a drawing of the specific
model number is enclosed, refer to that drawing for specific wiring.
CAUTION:
Certain dangers to human safety and to equipment may occur if some equipment is stopped without pre-warning. It is recommended that
monitored functions be limited to alarm only or to alarm before shutdown.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
