Running Delay Timer with Ramp Rate
Set the ramp rate as outlined in section 4.5.1.
Set the delay time as outlined in section 4.6.3.
When ramp rate is active with a delay timer the run indicator serves two functions:
• Indicates timer is running
• Indicates ramp rate is active
This means that when the timer has timed out the run indicator will still be illuminated if
the ramp rate is still active and will continue to be illuminated until the ramp reaches
setpoint, at which time it will switch off.
A characteristic of these combinations of parameters is that the scrolling text will
continue to indicate timer running when the timer has timed out. Checking whether the
timer has timed out or not can be done with the 'T.REMN' function. (see section 4.7.12)
The delay timer with ramp rate will function as outlined in the table above with the
addition of the functions in the following table.
