INSTALLATION GUIDELINES
SAFETY INSTRUCTION
MECHANICAL
vThe Controller in its installed state must be protected against
excessive electrostatic or electromagnetic interferences.
ELECTRICAL
vThe Controller must be wired as per wiring diagram & it must
comply with local electrical regulation.
vAmbient temperature and relative humidity surrounding the
Controller must not exceed the maximum specified limits.
vThe 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.

On Delay :- During Counter is in run mode; Output 1 still remain OFF. At the
completion of count; Output 1 change its state(ON) & remain in that state until user
press RESET or next cycle begins(in auto reset mode & TPR mode).
Off Delay (Interval) :- During Counter is in run mode; Output 1 get energised(ON).

Auto Reset Output Mode :- If selected; When relay contacts change its state after
the set value of count has been reached; it will remain in same position & wait for
end of auto reset time. On completion of this time, counter will reset i.e. relay
contact positions initialize depending on 'ON' or 'OFF' Delay mode selected
&counter will start counting again.
TPR Output Mode :- If selected; when relay contacts change its state after the set
value of count has been reached; Relays will remain in this state for 'TPR' time. On
completion of this time, relay contact positions initialize depending on 'ON' or
'OFF' Delay mode selected. Unlike Auto reset mode, counting continues during the
TPR time.
