ON/OFF TIME SETTING INSTRUCTIONS
FOR LOADS USING NORMALLY OPEN (NO) RELAY CONTACTS:
To set the INTERVAL ON time:
1. Set dial to the desired length of time that is required to elapse before the load (fan, light, etc.) is to be turned OFF. The dial can be set
to various positions within three different time ranges: 5-50 seconds, 1-50 minutes, and 1-3 hours. The dial can also be set to continu-
ous ON and continuous OFF positions.
2. The timer will begin timing the desired interval after the dial is set and the external contacts connected to the START terminal are
opened.
3. The timing interval can be restarted by closing and opening the external contacts connected to the START terminal.
To set for CONTINOUS ON:
Set dial and align the pointer to the ON position (approximately 12:00 o’clock position). The timer ignores any external trigger signals
in this mode. The green ON LED will illuminate steadily when the timer is set for a continuous ON condition.
To set for CONTINOUS OFF:
Set dial to and align the pointer to the OFF position. The timer ignores any external trigger signals in this mode. The red OFF LED will
illuminate steadily when the timer is set for a continuous OFF condition.
FOR LOADS USING NORMALLY CLOSED (NC) RELAY CONTACT:
The normally closed relay contact is provided to enable a secondary load to be switched at opposite time intervals of the main load (the load
controlled by the normally open contact.) When the load that is connected to the normally open relay contact is ON, the load connected to
the normally closed contact is OFF. When the load that is connected to the normally open relay contact is OFF, the load that is connected to
the normally closed contact is ON.
PROGRAMMING & OPERATING THE TIMER
OPERATING PARAMETERS
• The control relay will be energized continuously if the time interval dial is turned to ON. The control relay will be de-energized continuously if the time interval
dial is turned to OFF.
• The control will repeat cycle within 1% of timing range.
• The control will automatically reset after a 1 second power interruption and remain OFF with the red OFF LED illuminated steadily until the external contacts
connected to the START terminal is closed. If the external switch is closed during power failure, the load will turn ON with the green ON LED illuminated
steadily until the external contacts are opened.
• If the time interval dial is moved from one position to another during the active timing cycle, no change will result in the timing or output status for that cycle.
