applied for 5 seconds minimum, the accumulated
time will be stored in non-volatile memory when
power is removed.
To Reset: (for Resettable Models) Apply DC+ or AC
hot to pin 4 for 1/2second minimum while power (pins 1
& 2) is applied for 5 seconds minimum. The reset voltage must
be at the same level as the voltage used to power the unit.
703 Counter (AC/DC or DC Only)
To Display: Apply DC+ or AC hot to pin 1 and DC– or AC
neutral to pin 2. The display is activated at this point but the
count will not be started until a signal is applied to pin 3.
Note, for proper operation: Power must be applied to pins 1
& 2 before or coincident with pin 3.
To Operate: Apply DC+ or AC hot to pin 3. The count is
incremented when the input signal is removed from pin 3. The
input signal must be applied for 1/2second minimum (AC/DC
model) or for 1 millisecond mimimum (DC Only model). If
power (pins 1 & 2) has been applied for 5 seconds minimum,
the incremented count will be stored in non-volatile memory
when power is removed.
To Reset: (for Resettable Models) Apply DC+ or AC hot to
pin 4 for 1/2second minimum while power (pins 1 & 2) is
applied for 5 seconds minimum. The reset voltage must be at
the same level as the voltage used to power the unit.
4. OPERATION
NOTE: All models display an 8 in all digits for
1 sec. at power-up.
700 Hour Meter (AC/DC)
To Display & Operate: Apply DC+ or AC hot to pin 1 and DC–
or AC neutral to pin 2. The accumulation of elapsed time is
indicated by the flashing hourglass icon. If power has been
applied for 5 seconds minimum, the accumulated time will be
stored in non-volatile memory when power is removed.
To Reset: (for Resettable Models) Apply DC+ or AC hot to pin
4 for 1/2second minimum while power (pins 1 & 2) is applied
for 5 seconds minimum. The reset voltage must be at the
same level as the voltage used to power the unit.
701 Hour Meter (AC/DC or DC Only)
To Display: Apply DC+ or AC hot to pin 1 and DC– or AC neutral to
pin 2. The display is activated at this point but the elapsed time
will not be accumulated until a signal is applied to pin 3.
Note, for proper operation: Power must be applied to pins 1
& 2 before or coincident with pin 3.
To Operate: Apply DC+ or AC hot to pin 3 for 1/2second
minimum (AC/DC model) or DC+ for 1 millisecond mimimum
(DC Only model). The accumulation of elapsed time is indicated
by the flashing hourglass icon. If power (pins 1 & 2) has been 17

5. TROUBLESHOOTING
To maximize the life of this meter, please read all
instructions carefully and review Safety Precautions
on inside front cover of this manual. Most minor prob-
lems can be resolved by removing all power for at least
10 seconds and then reconnecting.
Problem Possible Causes
No Display Power not connected or too low.
Display Present, but Input (or enable) wire not connected.
counter does not activate. Start Input not connected.
Input voltage not reaching specified
minimum signal level.
LED not turning ON during Switch or switch-connection faulty.
activation condition.
6. MAINTENANCE
Curtis Model 700 & 732 Series hour meters are not serviceable
in the field. Units returned to the factory within the warranty
period (see inside backcover) will be replaced without charge.
!
732 Hour Meter (DC Only)
To Activate Display: Apply DC+ to pin 1 and DC- to pin 2.
To Activate LED: Apply DC+ (for active-high models) or DC-
(for active-low models) to pin 3 during indicator-on condition.
To Activate ElapsedTime: For models without separate
enable option - elapsed time is activated when power is
applied to pins 1 & 2. For models with enable option - apply
signal to pin 4. Note: Power (to pins 1 & 2) must be applied
before or at the same time as signal to pin 4.
Operation: Apply DC+ to pin 4 for 1 millisecond minimum.
Activation (accumulation) of elapsed time is indicated by the
hourglass icon flashing. Time accumulated will be stored into
non-volatile memory when power is removed, if power (to pins
1 & 2) has been applied for the minimum of 5 seconds.
Reset: (for resettable models), Apply DC+ to pin 4 for 1/2sec-
ond minimum, while power to pins 1 & 2 has been applied for
5 seconds minimum. Note: The reset voltage must be at the
same level as the voltage used to power the unit.
