Sensor Installation:
The explosion proof sensor is supplied with a slotted
mounting bracket. Sensors should be installed so the center
line of the magnets pass in fronf of the center line of the
sensor as the disc or wrap rotates. When using the pulser
disc, the center line of the magnetized area of the disc, shown
as Dimension S, in figure 1, is 1-3/4 inches from the center
hole of the disc.
The gap distance between the sensor and the disc or wrap,
Dimension A in the diagrams, is 3/8 inch ",118 inch. To achieve
the proper gap distance, adjust the position of the
explosionproof sensor, using the slots on the mounting
bracket.

Wiring:
AC Power Supply: Line TB1-1, Neutral TB1-2
The TR400-C Standard uses 115 Vac 6 VA at 60/50 Hz
with 230 Vac available as an option. External fusing must be
provided by the customer. The recommended fuse is 1/16
amp slow-blow.

Relay Outputs:
Output 1- TB3 and Output 2- TB3 the TR400-C offers 2 Form
C Relays. These relays are rated 250 Vac 5 A, and 30 Vdc 5
A resistive load.
Programming the Relay Outputs:
Relay Output Functions:
Each relay output has a set point value (Variables 07 and 10).
This value is compared to the displayed value on the front
panel and any action required is performed on the outputs.
Underspeed: De-energizes the output when the displayed
value is below the set point value.
Relay Programming Variables:
--------
Output 1
Set Point Value Variable 07
Output 2
Variable 10
Output Value: Enter the value at which the set point will de-
energize. There is a 1 % hysteresis for the value at which the
output will re-energize (i.e. Underspeed Set Point at 100 rpm
output will reset at 101 'pm, if On Time has expired).
Variable 02-PPR: Enter the pulses per revolution of the
sensor on the monitored shaft. Note: Electro-Sensors Model
907 Sensor with a Model 255 Disc will provide 8 PPR.

A Signal Input:
TB2-7 A Signal Input:
These inputs require a frequency input relative to speed.
Devices such as Hall-Effect Sensors, encoders or magnetic
pickups can all be used. Power for sensors is provided across
TB2-6 (+12 Vdc) and TB2-5 (common). The maximum power
draw available is 100 mA at an unregulated 12 Vdc. Wiring to
these inputs should be shielded cable with the shield tied to
TB2-5 only. Never use shielded æble wiih extra conductors.
Extra conductors act as antennas picking up electrical noise.
This is one of the most common reasons for electrical noise
on the frequency input signals. The default switch selection
settngs comply with Electro-Sensors Inc. sensors.
Diagnostics:
The relays may be tested by pressing the "." decimal place
button and holding it for 4 seconds. The relays will turn off as
long as the button is held. Releasing the button will reinitialize
the relays and include the start delay (Variable 6).

Entering Variables into the TR400-C:
To change a variable press the "VAR" key. The "PROG"
LED will light, and the display will read "Pr' followed by the
presently selected variable number. Press the "Â or T" keys
to change the value of the 1s location to the desired variable
number. Then use the".." key to move to the 1 Os position
and change the value to the desired variable number. Press
the "ENTER" key and the selected variables value will be
displayed, and the 1 s location will flash in the display window.
Press the "Â or T" keys to change the value of the 1 s
location. Use the "..~" keys to move to the 10s, 100s, or
1000s position (the selected position will flash) and then use
the "Â or T" keys to change the value. Press the "ENTER"
key to enter the new value. Pressing the "V AR" key without
pressing "ENTER" will keep the old value and return the
tachometer to the display mode.
