ETS-Lindgren 2090 Controller - Manual (Page 59)

Model 2090 Multi-Device Controller
The lower limit must always be less than or equal to the
upper limit.
USING THE SCAN FUNCTION
The SCAN key controls the cyclic motion of the attached
device. The SCAN function allows continuous scanning of
devices from one to an infinite number of cycles. The
SCAN function begins by moving to the closest limit, then,
from that point, the 2090 begins counting cycles. A cycle
is defined as movement from one limit to the other and
back again. The number of cycles that the device will
perform is defined in parameter P3 . The SCAN function
can be terminated by pressing the SCAN button a second
time (same behavior as pressing STOP) or by issuing any
other motion command.
