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 Elapsed Time: 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
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.
