APPLICATIONS
The RN-16T daily-weekly timer with the mains voltage monitoring option is a
microprocessor electronic device that functions as a voltage relay and a real time
relay. The RN-16T is designed for:
-- load energization/de-energization according to user-specified reset time /trip time;
-- de-energization an industrial and appliance single-phase 220V/50Hz load when
there are unallowable voltage variations in the mains. When the mains parameters
return to normal, the RN-16T automatically re-energizes the load.
The maximum number of events that the timer provides is: 60 = 30 ONs + 30 OFFs.
4 modes of operation:
I. A – identical events for all days of week;
II. 1-7 – different events for all days of week;
III. b -- identical events for 5 working days;
IV. C – identical events for 2 weekends of week.
The maximum number of events
in the A mode of operation: 7 х 60 = 420;
in the 1-7 mode of operation: 30 + 30=60;
in the b –C modes of operations: 5 х N + 2 х M, where N + М = 60, number of
events in the working days and weekends (for instance, if number of events in the
working days is N=40 and number of events in weekends is M=20 the maximum
number of events is
5 х 40 + 2 х 20= 240).
The RN-16T switches any power load:
• When the load power is below 3,5 kW (16A, AC1) de-energization is performed
directly through the relay output contacts that are connected in series with the
load power supply;
• When the load power is above 3,5 kW (16A) de-energization is effected by the
magnetic starter of the corresponding power (MS is not supplied in the complete
set) that has the relay output contacts to be connected in series with its coil
power supply.
DESCRIPTION
The timer is connected to the mains of 220V A.C. by the input (1-1) – (2-2)
contacts. The input contacts are provided with twin terminals for ease of wiring, i.e.
the 1-1 terminals is the first connection point and the 2-2 terminals is the
second connection point. The timer has the group of two-way break-before-make
output 3—4-4—5 contacts with a common 4-4 point. The load is connected through
the 4-5 contacts that break the load power supply circuit or the magnetic starter coil
power supply circuit. The 3-4 contacts are used in control & alarm circuits, if
necessary.
The setting of the real time, trip time and reset time, modes of operation
according to days of week as well as trip thresholds for voltage levels is effected by
the buttons «◄►, →), (→ » (see the section «Preliminary starting procedure and
service manual»).
When the relay trips for overvoltage/ undervoltage, the load is de-energized by the
break of 4-5 N. C. contacts that disconnect either the load power supply directly or
the magnetic starter coil power supply. The load will be automatically re-energized on
return to normal conditions when voltage parameters regenerate.

Note: Load de-energization for poor quality of the mains voltage doesn’t change
the time program mode of operation. Load energization occurs after the voltage
parameters have returned to normal considering the occurred event in accord with
the time program. If the mains voltage has been removed the parameter setting
will remain the same for not less than one month. At that the output contacts return
to the initial position corresponding to dead relay.
For instance, the timer is programmed for all days of week so that the last
energization occurs every day at 22.00 p.m., and the following de-energization
occurs next day at 08.00 a.m. Let’s assume that the voltage was removed on
Monday at 22.30 p.m. (the timer was in the load energization mode of operation)
and was applied on Wednesday at 06.00 a. m. At that after the voltage has been
removed the 4-5 contacts open and the 3-4 contacts close. According to the last
program instruction after the voltage has been applied the load is energized and
will be de-energized at 08.00 a.m.. If some other algorithm of energizations/deenergizations is selected for Wednesday then the timer output contacts take the
position corresponding to the last instruction when the voltage existed and they
will remain that position as long as the nearest time instruction for Wednesday
will be executed.
Preliminary starting procedure and service manual
Preliminary starting procedure offers such option as programming of real time for
a day of week and time of natural day, reset/trip time considering the day of week,
trip thresholds for overvoltage/undervoltage.
To apply a voltage to the timer means to connect the «1-1 – 2-2» input terminals
to the mains supply. Connection to the mains supply is effected according to the
safety regulations on dead timer. User must perform the operations as follows:

seconds with zero), that’s why the →) button is pressed at zero seconds.
** – If voltage monitoring or time operation modes specification is not required
they are not set; parameter reset is effected by the label «_» input into any point
of instruction.
If necessary, operation modes can combine in different conjunctions. The only
limitation is that number of events must not exceed 60.

Remember that number of events can not exceed 60, i. e. 30 energizations
and 30 de-energizations. The number of energizations and de-energizations
may differ.
After programming and in the operation user may view all the programmed
events. To this effect one needs step-by-step to enter (→)) every parameter by
menu buttons and to exit from menu ((→) with no parameter changed.
Note. To set time values user must specify all digits, «0» included, like that: 07.35
a.m. is to be set as «07.35», 07.35 p.m. is to be set as «19.35». Unspecified time is
displayed as «_ _ _ _». To delete an instruction one should put at least one space for
the instruction time (_7.35 – the time is deleted).
Load connection must be performed according to the safety regulations when
voltage is removed.
The programmed relay display shows the real time. The mains voltage value is
shown for 3 sec. every 15 sec.
