Setting Load Pickup Timer; Optically Isolated Input Settings - Advanced Power technologies TTC-1000 Instruction & Operation Manual

NOTE: Load pickup and drop out set points are according to the CT
bushing secondary current and must always be entered with a decimal
point and trailing 1/10's digit. For 3 amps you must enter 3.0. For .5 amps
you must enter 0.5.

4.7.2 Setting Load Pickup Timer

Programming Load Pickup Timer for the above illustrated Load Set Point 1 from
the front panel, press the
Press the YES button. The first digit will flash. Use the
scroll through the digits 0 – 9. Use the
digits. The currently active digit will flash. Press YES after you have entered all
digits.
The Pickup Timer for the other cooling bank can be changed by pressing the
arrow button to the corresponding Load Pickup Timer and following the above
procedure.
For programming from a PC just type the load set point pickup timer value on the
"Enter:" line as follows:
This will program the Load pickup timer to 120 seconds.

4.8 Optically Isolated Input Settings

The TTC-1000 may be optionally equipped with up to 14 optically isolated inputs.
Each input contains a limiting resistor that allows these inputs to recognize a
wide range of input voltage of 38 to 160 Volts AC or DC as being picked up.
Inputs 1 and 2 are scanned every 32 milliseconds. Inputs 3 through 14 are
scanned slightly less frequently. Every input's contact chatter is debounced by
requiring the input be stable for two scans before the new state is recognized.
Inputs may be assigned to any output using the programmable logic.
Each of the digital inputs can be set either as level active, LEVEL MODE or
PULSE MODE (positive or negative edge, depending on the INVERSION setting
for that particular input). For LEVEL MODE, the recognized state of IN1 or IN2
follows the voltage applied to the input. There is a built-in 64 millisecond
debounce time on all low to high voltage transitions for inputs 1 and 2. Debounce
time is slightly longer for inputs 3 through 14. There is no debounce delay on
high to low transitions. For PULSE, the recognized state of the input toggles
