* By default, Sensor type will be considered as PNP.
In case of NPN sensor type, NPN-COM to be shorted.
** For three wire sensor, connect the sensor to internal +12V as shown
or use external supply (5 to 30V) if required.
Note: If the sensors require more than 30mA current, use external power
supply to power the sensors. To reduce noise, Use of Snubber across load
is recommended.
Note:
1. In Configuration mode, Both the relays will turn OFF.
2. Set-Point High will only accept values greater than Set-Point Low. Also, both values should be Integer.

User Guide
Modes of Operation:
i) Under-speed Mode: The relay checks whether the speed of the
monitored system is lower than a particular set-point, dened as Set-
point Low. R2 is energized when the frequency of rotation becomes
lower than Set-Point Low.
ii) Over-Speed Mode: The relay checks whether the speed of the
monitored system is greater than a particular set-point, dened as Set-
Point High. R1 is energized when the frequency of rotation becomes
greater than Set-Point High
iii) Dual-speed Mode: The relay checks whether the speed of the
monitored system is within a particular range, dened as Set-Point
Low to Set-Point High. R2 is energized when the frequency of rotation
becomes lower than Set-point Low. R1 is energized when the frequency
of rotation becomes greater than Set-point High.
Note: Relay 1 has been assigned for Over-speed and Relay 2 has been
assigned for Under-speed by default. These cannot be interchanged.
Both the relays are NOT energized when the connected motor is operating
within the preset range.
Scale Factor:
The user programmable scale factor facilitates the direct reading in
desired engineering unit. The counter multiplies the number of pulses
received at the count input with the scale factor, and displays the result.
Rate display = Number of pulses received per minute x scale factor or No.
of pulses received per hour x scale factor.
The scale factor consists of two parts, mantissa and exponent. The
mantissa can be set from 0.001 to 9.999 and the exponent can be set
from -3 to +2.
The scale factor is arrived at as:
Scale factor = Mantissa X 10Exponent
Scale Factor cannot be 0 for obvious reasons.
Initial Time Delay (ITD): It is the time required by the motor to gain opti-
mum speed. When the ITD is entered and unit is powered ON, the unit
waits for the ITD to elapse (in addition to TTD) before switching the relay
outputs in case of any unhealthy condition.
Trip Time Delay (TTD): Sometimes the motor speed can go out of range
for a while. In order to avoid the relay tripping due to such momentary
changes in frequency, Trip time delay is provided. The relay trips only if
unhealthy speed ensues after TTD has elapsed.
Relay reset modes: This feature allows one to customize the operating of
both the relay outputs R1 and R2, according to one’s requirement.
Auto-reset: The relay outputs R1 and R2 become de-energized when the
speed of the connected equipment comes back to the prescribed range.
Manual-reset: Once the relay outputs R1 and/ R2 become energized, they
stay energized even after the connected motor or any supported equip-
ment comes back to healthy speed. In order to de-energize the relays, the
user will have to press the assigned key.
