Gate Switch input. The gate switch makes up when the elevator doors close.
When the switch is made, there will be 110 VDC on this input. When the switch
is open, there will be 0 VDC on this input. The gate switch may be wired in
series with other switches or locks on the elevator doors (as shown in the job
prints) so that if any of the switches do not make, the GS input will remain low
and the car will not run.
Door Lock Access Top input. When a top hoistway access is provided (see INA,
ATU, and ATD), the hoistway door lock associated with that landing is con-
nected between the #3 bus and this input. When the switch is made, there will
be 110 VDC on this input. When the switch is open, there will be 0 VDC on this
input and the car will not run unless INA is active and then only in response to
the ATU or ATD input.
Door Lock Main String input. If top and bottom hoistway access (see INA, ATU,
ATD, ABU, and ABD) is not provided, all hoistway door locks are wired in series
between the #3 bus and DLMS. When the switches are made, there will be 110
VDC on this input. When any switch is open, there will be 0 VDC on this input
and the car will not run.
Door Lock Access Bottom input. When a bottom hoistway access is provided
(see INA, ABU, and ABD), the hoistway door lock associated with that landing is
connected between the #3 bus and this input. When the switch is made, there
will be 110 VDC on this input. When the switch is open, there will be 0 VDC on
this input and the car will not run unless INA is active and then only in response
to the ABU or ABD input.
Door Contact Access Top input. When a top hoistway access is provided (see
INA, ATU, ATD, and DLAT), the hoistway door contact associated with that land-
ing is connected between the #3 bus and this input. When the switch is made,
there will be 110 VDC on this input. When the switch is open, there will be 0
VDC on this input and the car will not run unless INA is active and then only in
response to the ATU or ATD input.
Door Contact Main String input. If top and bottom hoistway access (see INA,
ATU, ATD, ABU, and ADB) is not provided, all hoistway door contacts are wired
in series between the #3 bus and DCMS. When the switches are made, there
will be 110 VDC on this input. When any switch is open, there will be 0 VDC on
this input and the car will not run.
Door Contact Access Bottom input. When a bottom hoistway access is provided
(see INA, ABU, ABD, and DLAB), the hoistway door contact associated with that
landing is connected between the #3 bus and this input. When the switch is
made, there will be 110 VDC on this input. When the switch is open, there will
be 0 VDC on this input and the car will not run unless INA is active and then
only in response to the ABU or ABD input.
Governor input. The governor is connected between the #3 bus and this input.
When the governor switch is made, there is 110 VDC on this input. It the gover-
nor switch trips/opens, there is 0 VDC on this input and the car will not run.
Spare input 1. If used, connect as shown in the job prints.
