USER’S OPERATING MANUAL FOR DIGITAL COUNTER
(Models: KCN - 448/778/998/668/888 )
SAFETY INSTRUCTIONThis controller is meant for counter applications. It is important to
read the manual prior to installing or commissioning of controller.
All safety related instruction appearing in this manual must be
followed to ensure safety of the operating personnel as well as
the instrument.
GENERALv The controller must be configured correctly for intended
operation. Incorrect configuration could result in damage to
the equipment or the process under control or it may lead
personnel injury.v The controller is generally part of control panel and in such a
case the terminals should not remain accessible to the user
after installation.
MECHANICALv The Controller in its installed state must not come in close
proximity to any corrosive/combustible gases, caustic
vapors, oils, steam or any other process by products.v The Controller in its installed state should not be exposed to
carbon dust, salt air, direct sunlight or radiant heat.v Ambient temperature and relative humidity surrounding the
controller must not exceed the maximum specified limit for
proper operation of the controller.v The controller in its installed state must be protected against
excessive electrostatic or electromagnetic interferences.
Ventilation holes provided on the chassis of the instrument
are meant for thermal dissipation hence should not be
obstructed in the panel.
ELECTRICALv The controller must be wired as per wiring diagram & it must
comply with local electrical regulation.v Care must be taken not to connect AC supplies to low voltage
sensor input.v Circuit breaker or mains s/w with fuse (275V/1A) must be
installed between power supply and supply terminals to
protect the controller from any possible damage due to high
voltage surges of extended duration.v Circuit breaker and appropriate fuses must be used for
driving high voltage loads to protect the controller from any
possible damage due to short circuit on loads.v To minimize pickup of electrical noise, the wiring for low
voltage DC and sensor input must be routed away from high
current power cables. Where it is impractical to do this, use
shielded ground at both ends.v The controller should not be wired to a 3-Phase supply with
unearthed star connection. Under fault condition such supply
could rise above 264 VAC which will damage the controller.v The Electrical noise generated by switching inductive loads
might create momentary Fluctuation in display, alarm latch
up, data loss or permanent damage to the instrument. To
reduce this use snubber circuit across the load.

DelayMode
ON
User can select among ON Delay / OFF Delay Mode described as follows,
ON DELAY: During Counter is in run mode; both Relay O/Ps still remain de-energised(OFF). At the completion of count ; both O/Ps change its state(ON) & remain in that state until user press RESET or next cycle begins(in auto reset mode & TPR mode).
OFF DELAY: During Counter is in run mode; Both Relay O/Ps get energized (ON). At the completion of count ; both relay O/Ps change its state (OFF) & remain in that state until user press RESET or next cycle begins(in auto reset mode & TPR mode).
PROGRAMMINGUSER LIST : To access the user list press SET key once.(All following selected parameter’s code as shown in shaded will be displayed for01 sec. followed by their values / options)
CONFIGURATION MODE: 1. TO ENTER IN THIS MODE: PRESS AND HOLD DOWN "SET" KEY FOR 3 SEC. AT POWER ON.2."CNFG", "LIST" MESSAGE WILL BE DISPLAYED ON UPPER & LOWER DISPLAY RESPECTIVELY AND IT WILL REMAIN STEADY FOR 3 SEC. NOW UNIT WILL ALLOW THE USER TO CONFIGURE DIFFERENT PARAMETERS WITH OPTIONS AS DESCRIBED BELOW. 3. PRESS UP OR DOWN KEY TO SCROLL BETWEEN THE PARAMETER OPTIONS. 4. USE Up/Down/Shift KEY TO SET NUMERIC VALUES OF THE PARAMETERS.ALL FOLLOWING SELECTED PARAMETER CODE AS SHOWN IN SHADED WILL BE ON THE LOWER DISPLAY AND THEIR OPTIONS VALUE WILL BE DISPLAYED ON THE UPPER DISPLAY.
In normal mode, The lower display shows the value of 'set count' while the upper display shows the actual value of count (in accordance with the scale) given at the input terminal. If 'Front reset' is enable than the value of count can be reset by pressing reset/dn key.
In normal mode, Press the 'up' key to view the present value of Bach count. 'B.CNT' will be displayed on the lower display & the present value of 'Bach count' will be displayed on the upper display. The Bach led flashes every 500ms to indicate' view mode'. If batch reset is enabled than the Bach count can be reset by pressing the reset/dn key for 3 sec. Press the 'set' key or wait for 3sec to exit this mode.

User can select Output mode among LO/TPR/Auto Reset described as follows,
TOGGLE OUTPUT MODE: If selected ; when actual counts reaches its set value ,Relay O/Ps will get l changes its state.
AUTO RESET OUTPUT MODE : 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(it can be set by user). 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. There are two different modes of operation in auto reset mode.

This parameter lets the user enable/disable the count reset from down/reset key.
DISABLE: If selected; user can not reset the counter by pressing down key located at front
panel. Only remote reset at back terminal is allowed. This feature is useful to avoid unauthorized
attempt to reset the counter during run mode.
ENABLE: If selected; user can reset the counter by pressing down key located at front panel.
Auto ResetTPR 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 (it can be set by user). 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. There are two different modes of operation in TPR mode.

MODE 2: In TPR Mode2, User ca set two different ON/OFF time for both relay output as per the ON/OFF Delay.
MODE 1: If selected; user can set 'Auto Reset/TPR' time. The On/OFF time for first relay output
is same as 'Auto Reset/TPR' time. In case of auxiliary operation, 2nd relay will have same on/off
time.(if used for Bach operation 2nd relay remains on after set Bach count has been reached)
This parameter occurs only if 'Auto Reset 'or 'TPR' mode is selected. User can select any one of
the two modes described below:

This parameter occurs only if Latch o/p mode is selected. User can enable/disable counting after set value of count is reached.
Enable: If selected; counting continues after the set value of count is reached. Only the o/p remains latched thereafter until count is reset.
Disable: If selected; counting stops after the set value of count is reached. The o/p & count remains latched thereafter until count is reset.

restored ; counter will be re-set & counting will restart(depending on the output mode)
ENABLE: If selected ; when power fails during counter is running ; counter will continue

selected) at the time when power is restored.
This feature enables user to select memory back up facility at the time of power fail during timer is running.
