SAFETY INSTRUCTION

All safety related instruction appearing in this manual must be followed to ensure safety of the operator as well as the unit..

MECHANICAL

• Ambient temperature and relative humidity surrounding the Timer must not exceed the maximum specified limits..
• The Timer in its installed state must be protected against excessive electrostatic or electromagnetic interferences.

ELECTRICAL

• The Timer must be wired as per wiring diagram & it must . comply with local electrical regulation.
• The Electrical noise generated by switching inductive loads might create momentary Fluctuation in display, latch up, data loss or permanent damage to the instrument. To reduce this use snubber circuit across the load.

Enable : If selected, user can view & edit Hold time in user list.
Disable : If selected, user can only view th Hold Time but cannot edit it in user list.| ENABLE
TIMER
DIRECTION| | | TIMER COUNTING DIRECTION :
UP COUNTING : If Selected, timer starts counting from 0 to set time in ascending| DOWN

order. ( Up direction )
DOWN COUNTING : If Selected, timer starts counting from Set time to 0 in
descending order. ( Down direction )
TIMER
START| | | TIMER START MODE : This parameter defines the Start mode for the timer.| POWER
ON
START
POWER ON START : If Selected , Timer starts counting at Power On.
FRONT START : Timer starts only after user presses START key. If the cycle is
incomplete at the time of power fail , It will continue after power is restored without need for re-issuing the Start command from front key ( If MEM=On ). Not valid for CY3 mode
FRONT START : Timer starts only after user presses START key. If the cycle is not over at the time of power fail, It will not start till the START command is issued from the front panel (If MEM=On). Not valid for CY3 mode.
REMOTE START ( EDGE TRIGGERING ) Timer starts counting only when it
detects high to low pulse at back terminal from external Input.
REMOTE START WITH LEVEL SENSING Timer starts counting only when it
detects high to low pulse at back terminal from external Input. The input signal must remain low during timing cycle otherwise timer will Reset.
TIMER
MODE| | | TIMER MODE : Prompted only if selected function is ON/OFF Delay & start input is| LATCH

other than power on start. For power on start this function is always set to LO
BeideHED MODE : In this mode once the timing cycle is over, User must issue a Reset signal from front key( if F.rt= On) or Ext. Reset input to re-start the timer.
AUTO RESET MODE : In this mode once the timing cycle is over, Next start input either thro’ Front panel or thro’ external input signal will re-start the timer.
GATE
INPUT| | | GATE INPUT : Prompted only if Timer is configured for either power on start or| NO
front start. When enabled ( Set to yes ) the external input can work as a Gate input. DISABLE (nO) : The external input can not be used as a Gate input.
ENABLE (YES) : The external input can be used as a Gate input.
FRONT
RESET| | | FRONT RESET ENABLE/DISABLE : This parameter allows the user to Enable or| YES
Disable front Reset function. This feature prevents un-authorized attempt to Reset the Timer during Run mode.
DISABLE (nO) : The Timer can not be reset through front panel.
ENABLE (YES) : The Timer can be reset through front panel.
MEMORY
BACKUP| | | MEMORY BACKUP ENABLE/DISABLE : This parameter allows the user to| NO
Enabe or Disable memory backup function.
DISABLE (nO) : No memory backup for run time value.
ENABLE (YES) : Memory backup for run time value.
OUTPUT 2
FUNCTION| | | OUTPUT 2 FUNCTION : This parameter will be prompted only if selected Timer| AUC
function is either ON or OFF delay. Not applicable for Cyclic modes.
END OF CYCLE OUTPUT : The OP2 is energized for rt period set in user list at the
end of timing cycle.
AUXILLIARY CONTACT : The OP2 will operate simultaneously with OP1. This
function is required when user needs 2 changeover Relay contacts.
INSTANT CONTACT : The OP2 function as a instant contact which operates
immediately when timer starts & remains in that state till the start of next cycle. OFF : The OP2 is not used & can be kept reserve for future use.
