Technical Specications
Art.701T BST/GMT Time Clock
The Art.701T is a digital time clock with BST/GMT automatic correction, back lit LCD display and trade button
input. The time clock is already pre-wired within the cabinet from one of the 13.8Vdc fused outputs on the
UBPSU5.0 PSU. It incorporates a dry contact 3A rated relay (CO, NO and NC).
Includes six fully programmable ON/OFF times, they can be set for a single day of the week (Mon - Sun),
weekends (WE), week days (WD) or all days (AD). To disable an ON/OFF time simply set the ON time the same
as the OFF time. In the event of a power failure the on board battery back-up will maintain the correct time
and all the time bands that have been setup.
Programming and setup of the time clock is carried out by using the four push buttons: MODE, UP, DOWN
and SELECT (on/o) just below the LCD display and the two internal jumpers JP1 and JP2. The MODE button
advances through the dierent programming modes starting with mode 1 which allows the editing of the
time and date. Modes 2 – 7 allows the editing of the time bands. Mode 8 allows the editing of the relay time
in trade mode only (mode 8 will only appear on the display when the time clock is in trade mode this is done by
setting jumper JP1 in the A position, also see notes below). The UP, DOWN buttons allow the information to
be edited and the SELECT (on/o) button moves the cursor to the next input eld on the display (refer to
the programming ow chart on page 14). If the time clock is inadvertently left in programming mode it will
automatically revert to standby mode after a preset time.
Jumper JP1 sets the time clock in either trade mode (JP1 in position A) or time clock mode (JP1 in position
B). When in trade mode the on board relay is only triggered when the terminal inputs TR and - (connected
directly to a trade button on the intercom door panel) are shorted together. The on board relay will trigger
for the relay time set in mode 8 and will only be active during the time band/bands (6 programmable time
bands 1 - 6 are available) setup in modes 2 - 7. When in time clock mode the on board relay is automatically
triggered when the time clock enters the time band/bands set up in mode 2 - 7. The on board relay will switch
from NO (normally open) to NC (normally closed). Once the time clock reaches the end of the time period it
will switch back from NC to NO. When the jumper JP1 is set to position B mode 8 will not be available in the
programming menu.
Programming Modes
Jumpers JP1 and JP2
Jumper JP2 enables or disables the time clock’s BST/GMT correction feature. When JP2 is in position A the
automatic British Summer Time correction feature is disabled. When JP2 is in position B the automatic British
Summer Time correction feature is enabled (the default position for JP2 is set to the B position).
