Calculating minimum (Rmin) and maximum (Rmax)
revolutions
In all of the above cases, the number of revolutions the
encoder transmits must fall within a calculated minimum and
maximum range. If the encoder's output exceeds or falls below
this range, the number of revolutions will not be displayed
accurately. Also, the tachometer cannot represent values
greater than 10,000, even if the calculated value indicates
otherwise.
Installation
Calculating the maximum number of revolutions (Rmax)
When displaying in rpm:
Rmax = 10,000 x 60/A (rpm) or 10,000 (rpm),
whichever is smaller.
When displaying in rps,
Rmax = 10,000/A (rps)
Calculating the minimum number of revolutions (Rmin)
With selector switch at DIVIDE position
Rmin = 1 (rpm or rps)
With selector switch at MULTIPLY position
Rmin = 60/A (rpm)
s WIRE-WRAP TERMINALS
The terminals used on H7E wire-wrap models have a cross
sectional dimension of 1 x 1 mm. Select one of the three
gauges of wire from the table at right. Also listed in the table
are the appropriate wiring hardware.

s CAUTIONS CONCERNING THE H7ER TACHOMETER
On some H7E models, the power input terminal and the
common signal input terminal (terminals 2 and 4) are internally
short-circuited. Pay special attention to polarity when wiring
these terminals.
Keep the input wiring as short as possible.
Whenever possible, avoid routing the input wiring of the AC/DC
voltage input type in parallel with 200 to 240 VAC power lines.
If the input wiring must be routed together with the power lines,
keep the length of that portion of wire running parallel with the
power lines to within 20 m (65.6 feet).
When using shielded wire, stray capacitance may occur. The
operation of the tachometer might be affected when using wires
which have a capacitance which exceeds 500 pF (about 10 m,
32.8 feet, with parallel wires of 2 mm2). Keep all wires as short
as possible.
s HOW TO MOUNT THE TACHOMETER
Insert the H7ER tachometer from the front of the mounting
panel. Slide the mounting bracket into place from the rear of
the panel, and tighten the knurled nut by hand. Do not use tools
(such as pliers) to tighten the nut. Excessive tightening may
damage the tachometer. Wire-wrap terminal models may be
back-mounted, by soldering the terminals to a printed circuit
board.
NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches, divide by 25.4.
