INSTALLATION AND OPERATION INSTRUCTIONS — FENCE PROTECTION SYSTEMS
Transducer Service Kit (TSK) Installation
Transducer service kits (TSK) are required for all end of line termination and splicing of standard
transducer cable. TSK installation is very important to be sure that moisture does not affect transducer
cable operation. When a double run of sensor cable is installed, utilize the end-of-line termination
located inside the pre-amp enclosure. A separate TSK is not required.
Each TSK consists of the service kit enclosure, a 1 Megohm, 1% metal film resistor preinstalled on the
terminal block, and a cable tie for fastening to the fence fabric. The service kit enclosure is molded of
sunlight resistant polymer with a conductive (copper) inner surface to maintain a proper shield around
the termination. See Figure 42.
Proper preparation and installation of the transducer cable is essential to provide a water tight seal
within the TSK. TSKs must always be installed with the cable entering the bottom. Each cable must
have a drip loop so moisture is not allowed to collect near the cable openings. After splicing or termi-
nation, each TSK should be filled with Dow Corning 4 electrical insulating compound before sealing.
The Dow 4 compound will keep moisture away from the terminations.
The transducer cable shield must be properly stripped and installed to contact the TSK copper shield-
ing saddle on the inside edge of the cable entry. The inner conductor must be trimmed to the proper
length to reach the termination screw.
To prepare each end of the transducer cable for TSK termination, proceed as follows:
(Refer to Figure 43.)
Step 1: Strip outer insulation 1 inch from the end.
Step 2: Pull braided shielding back 3/4 inch from center conductor and twist for insertion into
terminator receptacle.
Step 3: Strip center conductor insulation back 1/4 inch from the end and insert into one side of
terminator receptacle and tighten lock screw.
Step 4: Insert twisted shield into terminator receptacle next to center conductor and tighten lock
screw.
NOTE:
Prior to installing service kit cover, ensure the transducer outer insulation fits at
the inside edge of the cable saddle on the service kit and that the shield contacts the
saddle. This is very important to maintain a proper seal. Insulation too far inside the
service kit may hinder closing the top cover and too far out may allow moisture to
penetrate the enclosure. This may also interrupt the enclosure shield and allow EMI to
enter the system.
Step 5: If splicing two sections of transducer cable, remove the preinstalled 1 Megohm resistor from
the terminal block.
Step 6: Fill the TSK completely with the Dow Corning 4, or other approved, silicone grease.
Step 7: Install top cover, being sure it seats on all sides, and attach to the fence with a single cable tie.
CAUTION:
Use only factory supplied or 1% metal film EOL resistors. Carbon and other
resistors are not stable and must not be used.
