H/WAY
ATU Hoistway Access Top Up switch input. When the Car Panel Access Enable
switch (INA input) is on, an active input (key switch closure) here (110
VDC) will cause the car to move up the hoistway. A hoistway limit switch
electrically between the ATU input and the activating switch will open and
stop the car after it has moved the required distance up the hoistway (if
installed). Normal/Off state = 0 VDC. Refer also to the -MRW drawing in
the job prints.
ATD Hoistway Access Top Down switch input. When the Car Panel Access
Enable switch (INA input) is on, an active input (key switch closure) here
(110 VDC) will cause the car to move down the hoistway. A hoistway limit
switch electrically between the ATD input and the activating switch will
open and stop the car after it has moved the required distance down the
hoistway (if installed). Normal/Off state = 0 VDC. Refer also to the -MRW
drawing in the job prints.
ABU Hoistway Access Bottom Up switch input. When the Car Panel Access
Enable switch (INA input) is on, an active input (key switch closure) here
(110 VDC) will cause the car to move up the hoistway. A hoistway limit
switch electrically between the ABU input and the activating switch will
open and stop the car after it has moved the required distance up the
hoistway (if installed). Normal/Off state = 0 VDC. Refer also to the -MRW
drawing in the job prints.
ABD Hoistway Access Bottom Down switch input. When the Car Panel Access
Enable switch (INA input) is on, an active input (key switch closure) here
(110 VDC) will cause the car to move down the hoistway. A hoistway limit
switch electrically between the ABD input and the activating switch will
open and stop the car after it has moved the required distance down the
hoistway (if installed). Normal/Off state = 0 VDC. Refer also to the -MRW
drawing in the job prints.
