When the input is activated the output will turn on. The Output will return to the “off”
state when the delay expires or the input is removed before the delay expires or the
reset is activated before the delay expires.
A momentary on pulse is generated on the output at the beginning of every time period
as determined by the value set at (A). The period value (A) is in seconds and the
minimum value which can be set is 0.02 seconds. The sync input (B) will reset the
period timer back to zero when activated allowing the pulse to become synchronised
with another timed function.
The Heartbeat Block would typically be used to trigger an event at a regular interval, for
example, it could be used to activate an Analogue Store to store a temperature every
minute.
Note: The use of a SR latch block may be required.
The output displays the total number of hours that the input is
active. The output is shown to one decimal place. The output
will go to zero when the reset input is active (On). The hour
count is stored in the Mercury Intuitive TDB controller memory
on the hour and half past the hour. The maximum hour count
is 596,680 (which equates to 68 years)
