With the relay turned off, the contacts between terminals N/O — Com (3 and 4) are opened and the
relay contacts between terminals Com — N/C (4 and 5) are closed. If the Timer 031 switches to
UnOccupied mode, the UNOCC element is displayed and the internal relay is turned on. With the
relay turned on, the contacts between terminals N/O — Com (3 and 4) are closed and the relay
contacts between terminals Com — N/C (4 and 5) are opened.
Schedule Override
The Timer 031 allows the user to override a given event temporarily or permanently. During a
temporary Override the Timer skips one single event. With a permanent Override, the Timer
remains continuously in either the Occupied or UnOccupied mode until the Override is manually
cancelled. The Override options are described in the Settings section in this brochure.
Temporary Occupied Override
When the Timer 031 is in Occupied mode and a Temporary Occupied Override is selected, the
OVR element is flashed and the Timer skips the next UnOccupied event.
When the Timer is in UnOccupied mode and a Temporary Occupied Override is selected, the
OVR element is flashed and the Timer immediately switches to Occupied mode.
Note: The OVR element turns off when the Temporary Override is terminated at the next event.
Temporary UnOccupied Override
When the Timer 031 is in Occupied mode and a Temporary UnOccupied Override is selected,
the OVR element is flashed and the Timer immediately switches to UnOccupied mode.
When the Timer is in UnOccupied mode and a Temporary UnOccupied Override is selected,
the OVR element is flashed and the Timer skips the next Occupied event.
Note: The OVR element turns off when the Temporary Override is terminated at the next event.
The tekmar Timer 031 is a microprocessor-based timer which can be programmed to provide up to
two Occupied and two UnOccupied events per day for each day of the week. The Timer 031 operates
its internal SPDT relay based on the programmed schedule. The Timer 031 allows the user to over-
ride any programmed event temporarily or permanently.
In case of power shut down, the programmed information is retained in memory for at least 10 years.
The clock continues to operate using a backup battery for up to 24 hours, at which time it automati-
cally shuts itself down.
When used with a tekmar control, the Timer 031 has a special function which synchronizes the Occu-
pied / UnOccupied schedule with the Optimum Start / Stop feature on the tekmar control.
By cutting the jumper in the wiring chamber, the Timer 031 can be used in a non-60 Hz power system.
POWERING UP THE TIMER
After the Timer 031 is powered up, a number indicating
the software version is displayed for 1 second. Following
this, all elements are displayed for 4 seconds. If the
C US
R
158033
Timer has been turned off for more than 24 hours, the
Timer flashes 12:00 AM, the OCC element, and the Su
pointer to indicate that the clock must be set. Setting of
the clock is described in the Settings section of this
brochure. When power is removed from the Timer, the
OVR
display is turned off; however, the time clock continues
to operate on the backup battery for up to 24 hours. The
battery is generally good for forty 24 hour shut down
periods.
Occupied / UnOccupied mode
The Timer 031 has an internal relay which switches on
and off according to a programmed schedule of Occu-
pied and UnOccupied events. The Timer 031 allows up
3 4 5
to two schedules for each day of the week. During the
N/O Com N/C
first schedule, the Timer turns on the 1 display element
and during the second schedule, the Timer turns on the
2 display element. Each schedule has an Occupied and
UnOccupied event. When the Timer is in Occupied
mode, the OCC element is displayed and the internal
relay is turned off.
