RESET switch remains active even when you connect a remote reset switch so that
high voltage can be shut down from either location.
The Remote File Select function gives you the capability to quickly change parameters
and initiate a test remotely. You can access Ten pre-programmed test files by
connecting pins 1, 6, 8 and 9 to the common pin 7, in different combinations. The
memory select bits should be set simultaneously and remain set for a minimum of
20ms to guarantee that the correct memory will be selected. However, the memory
select bits may be set in sequential manner, provided that the time delay between
each bit is less than 4ms. When the desired bit pattern has been established it should
remain set for a minimum of 20ms to guarantee that the correct memory will be
selected. The
Remote File Select Truth Table (binary) shows the different
combinations of momentary switch (relay) closures, and which memory programs that
will be selected as the result. It may be necessary to "OR" the momentary switches
(relay contacts) to prevent incorrect program selection due to timing errors.
