WARNING
To select option HSEL 3 or HSEL 4, the SSEL option
selected in 1.5 MUST have been SSEL 4 since the trip
can only operate on either speed or hours, not both.
The desired option is selected in the same manner as in 1.5, the SSEL option.
To move to the next screen after selecting the desired HSEL option, momen-
tarily press and release the push button.
1.5.3
Preset/Reset Hours (HOUrS) Screen
The next screen will be “HOUrS”. This screen precedes the programming screen
used to either preset the hourmeter to a specific value or to reset the hourmeter to
all zeros.
To move to the programming screen, momentarily press and release the push
button. The screen will display, on a new unit, “00000” or, previously operated
hours with the most significant digit (the left-most digit) blinking. To change the
value of the blinking digit, press and hold the push button for at least one (1) second.
The digit will increment and roll over to zero (0). When the desired value is obtained,
release the push button.
To move to the next digit, momentarily press and release the push button; the next
digit will blink. Once all the digits have been programmed, move to the next screen
by momentarily pressing and releasing the push button.
1.5.4
TRIP Value (triP) Screen
The next screen will show “triP”. This screen precedes the programming screen
used to set the value of the trip setpoint. This value can represent hours or RPM
depending on the SSEL (section 1.5) and the HSEL (section 1.5.2) options
selected.
To move to the programming screen, momentarily press and release the push
button. The screen will display, on a new unit, “99999” or, a previously programmed
value with the most significant (left-most digit) blinking.
Programming is accomplished in the same way as described in section 1.5.3.
Once all the digits have been programmed, move to the next screen by
momentarily pressing and releasing the push button.
Examples:
00327 = 327 RPM or Hours
10005 = 10,005 RPM or Hours
