INTRODUCTION
PURPOSE
The TK84 Optical Package consists of the TK84 Temporary Transducer
Interface, optical Keyphasor sensor, optical Keyphasor mounting kit,
cables, reflective tape, carrying case, and manual
as shown in Figure 1.
The TK84 Temporary Transducer Interface is a two-channel, portable
unit. Channel A
is a signal conditioner for an optical Keyphasor
transducer. Channel B
is a power source for a proximity probe
transducer. Use the TK84 with diagnostic equipment as an optical
Keyphasor trigger input or to temporarily power proximity probe
transducers during machine assembly, probe installation, or machine
balancing.
FEATURES
• Portable (Low weight, small size)
• Low cost
• Battery powered
• Optical Keyphasor and Proximitor power supply in one unit
• Magnetic or clamp mounting for temporary optical pickup

LL WARNING
Contact with rotating machinery causes
severe injury. Be careful; keep safe
distance.
POWERING TRANSDUCER INTERFACES
The TK84 Temporary Transducer Interface powers transducers such as
Proximitors or Bently Nevada Corporation accelerometer interface units.
The output power is -24 Vdc at 12 mA maximum. This is adequate to
power one Proximitor or accelerometer interface unit. Figure 2 shows the
necessary connections. Test leads and alligator clips are supplied with the
package for making these connections.
OPTICAL KEYPHASOR TRANSDUCER
Refer to Figure 3 and the steps below to install the mounting kit.
1. Clean shaft surface.
2. Place reflective tape on shaft. A one-inch square of reflective tape is
adequate for most shafts.
3. Install optical Keyphasor sensor in pickup holder. Secure with lock
nuts.
4. Install pickup holder, with optical Keyphasor sensor attached, in the
end of the gooseneck. Tighten pickup holder locking knob.
5. Connect gooseneck to magnetic base using the threaded adapter. (An
alternate mounting method is with the vise grip pliers. Do not use the
threaded adapter when connecting gooseneck to vise grip pliers.)
6. Mount the magnetic base (or vise grip pliers) on the machine.
7. Loosen lever and adjust gooseneck so pickup is about 3 inches from
shaft. Do not bend gooseneck more than 90 degrees.
8. Tighten lever to secure gooseneck.

It may be necessary to adjust gooseneck tension
using tension adjustment. Loosen lock nut and
turn tension adjustment clockwise (viewed from

9. Connect optical sensor cable to TK84 PROBE A connector.
10 . Connect TK84 OUT A to a voltmeter (To use the TK83 Balance

2, connect to the SIGNAL connector in the DIRECT/GAP
mode).
11. Set TK84 CHAN A switch to ON. Make sure BATTERY OK light is

IN CASE OF DIFFICULTY
TEST AND VERIFICATION
Perform the following checks to be sure the TK84 is functioning properly.
1. Visually inspect for physical damage to case, connectors, and switche s.
2. Set CHAN A switch to ON and CHAN B switch to OFF. UATTERY
OK WHEN LIT indicator should come on;
If not, replace battery.
3. Set CHAN B switch to ON and CHAN A switch to OFF. BA TIER Y
OK WHEN LIT indicator should come on;
If not, replace battery.
4. Connect Proximitor to POWER and COM terminals to provide load.
(You can use a 3K ±
500 ohm resistor if a Proximitor is not available.)
5. Set CHAN B switch to ON.
6. Connect DC voltmeter between POWER and COM terminals and
measure the voltage. It should be from -22 to
-26 Vdc.
7. Set CHAN B switch to OFF.
8. Connect optical probe cable to PROBE A connector.
9. Connect TK84 OUT A to voltmeter (You may use a TK83 Balance
Master
2. Connect to TK83 SIGNAL connector in the DIRECT/GAP
mode).
10. Set TK84 CHAN A switch to ON.
11. Place a reflective target (white paper or other reflective object) in
front of optical sensor. The voltmeter (or TK83) reading should be
greater than 5 Vde when you put the target in front of the probe, and
drop to less than 0
.5 Vdc when you remove it.
