Multi-display 8-Channel Timer

755-HM8

Each of the 8 channels of the 755-HM8 timer operates in an identical

1

manner.







To cancel any operation in progress, press the related channel button
three times in quick succession.

Operation

The timer counts down from the programmed time value of the first duty function. Every three to five
seconds during the countdown the display briefly shows the name of the current duty function and
then returns to the remaining time value. When the time value reaches 0:00, an alarm sounds (if
enabled) and the display alternates between the name of the just completed function and 0:00. The
alarm can be set to function in one of several possible manners for each enabled duty function (see
section on alarm programming). Each duty function is also equipped with an alert function. When
the programmed alert time is reached during the countdown (see section on Alert Programming), an
alarm sounds for approximately five seconds and the associated LED flashes.







Each channel has a multi-colored LED indicator that shows the status
of the current duty function. The indicator has three colors: green,

3

yellow, and red. The indicator is green during the first 70% of the
countdown for the current duty function. It changes to yellow during
the next 20% of the countdown. It is red during the last 10% of the
countdown and begins to flash when the countdown is completed.

This sequence is repeated for each enabled duty function (maximum of six)
of this channel. If a duty function’s time value is set to 0:00 (see section on
programming) this function and all subsequent functions for this channel
are disabled and not part of the channel’s timing sequence.







NEVER use any instrument or object to activate the channel buttons.
Press the buttons with your finger ONLY. Such misuse may damage
the unit, voiding the Warranty.

Channel Defaults

Press the button of the channel with the flashing red indicator to cancel that channel’s alarm (may
be programmed to automatically cancel alarm). If another duty function is enabled (maximum of six)
and the alarm mode is set to continue (see section on alarm programming) the timer automatically
begins to count down the time value of this new duty function as soon as the previous duty function
is completed. This happens in the background even while the alarm from the previous duty cycle is
still activated. Only when the alarm is cancelled is the time value for the new duty function
displayed. As the countdown continues, every three to five seconds the display briefly shows the
name of the current duty function and then returns to the remaining time value.

FOR EXAMPLE: When the button for Ch. 1 is pressed, the timer begins counting down from 42 secs.
and the word “FRY” is displayed every 3-5 seconds. When the 42-sec. fry time has completed, an
alarm sounds. Pressing button #1 for turns off the alarm and automatically starts the next cycle: a
30-sec. cycle with the word “DR_N” displayed every 3-5 secs. At the end of the 30-sec. Drain cycle,
the alarm sounds again. Pressing button #1 will turn off the alarm and automatically start the last
cycle in the program: a 15:00 min. cycle with “HOLD” displayed every 3-5 secs. At the end of the
Hold cycle, a final alarm will sound. Pressing button #1 will turn off the alarm and the timer will
return to the ready position, with “- - - -” displayed.
