3.2.3 Floor Control Relay Settings
Each of the 16 floor control relays on the 2348-010 elevator control board can be set to operate as
either a normally open (N.O.) or normally closed (N.C.) device. This is accomplished by the shorting
pins located next to each of the relays. SW-1 switch 8 also affects these 16 relays and how they
operate. If SW-1 switch 8 is in the OFF position, the 16 elevator button relays on the board will not
energize when power is applied to the board. If SW-1 switch 8 is in the ON position, the 16 elevator
button relays on the board will energize when power is applied to the board.
NOTE: The setting of SW-1 switch 8 does not affect the LOBBY HALL UP CALL relay. Refer to
3.2.4 for more information on the CALL relay.
The normal (and recommended) settings for the 16 floor control relays is N.C. (normally closed). This
provides normal elevator button operation should the 2348-010 board(s) lose power or become
disabled by any other means. Likewise, the normal (and recommended) setting for SW-1 switch 8 is
ON so that when the 2348-010 board powers up, all 16 elevator button relays on the board will
energize and thus result in an open output circuit since the relays are set for N.C. operation. If the
relays are set for normally open (N.O.) operation and the 2348 board loses power or becomes
disabled by any other means, the floor buttons in the elevator will work.
3.2.4 Lobby Hall Up Call Relay
The LOBBY HALL UP CALL relay is a special relay on the 2348-010 elevator control board that can
be programmed to "call" the elevator to the lobby or ground floor when a visitor is granted access by
the access control system. Only the LOBBY HALL CALL relay on the system MASTER board(s)
activates when access is granted. The LOBBY HALL CALL relay feature is turned on or off by SW-2
switch 8, and like the other relays on the 2348-010 board it can be set to operate as either a normally
open (N.O.) or normally closed (N.C.) device. The normal setting for the LOBBY HALL CALL relay is
N.O.
If SW-2 switch 8 is in the ON position, the LOBBY HALL CALL relay WILL NOT activate when access
has been granted. If SW-2 switch 8 is in the OFF position, the LOBBY HALL CALL relay WILL
activate when access is granted and will cause the elevator car to go to the lobby (or whatever floor
the call relay has been wired to) floor. The setting of SW-2 switch 8 also affects the start of the time
allowed for the floor control relays to be active. When this switch is in the ON position, the time that
the floor control relay(s) activates begins immediately after access has been granted. If the switch is
in the OFF position, the time begins only after the ground floor detect input is activated on the 2348-
010 board.
Careful thought should be given to this function. If the switch is in the ON position (lobby hall call
feature is turned off), the time setting in the software must be set high enough to allow the elevator to
reach the first floor from the top floor, and allowance must also be made for the time it takes a visitor
to reach the elevator after they have entered the building. For example, if the time in the software
was set to 30 seconds, but it takes the elevator 45 seconds to reach the first floor from the top floor,
the amount of time that the floor control relay is active will have expired by time the elevator reached
the first floor. The visitor will find that the buttons in the elevator are inoperative.
When SW-2 switch 8 is in the OFF position (lobby hall call feature is turned on), the time that the floor
control relay(s) are turned on begins when the ground floor detect input on the 2348-010 board is
activated. Note that if lobby hall call is used, a ground floor detect input must be received by
the 2348-010 board, otherwise the floor control button(s) will never become active.
For information on programming the amount of time that the floor control relays are turned on, refer to
the Remote Account Manager User's Manual (P/N 1835-066).
