Reaction times

The total reaction time is the sum of:
Reaction time of the motion monitor
De-energisation time of the output relay (<20ms).
Delay of de-energisation on any external switching devices.
The reaction time of the motion monitor decreases as the speed to be monitored increases (linear).
It measures at 5 Hz about 200 ms and at 800 Hz about 1 ms
of DNDS 2C, 2D, 2GA
Installation
The equipment must be cabinet mounted min. IP 54). The Equipment is equipped with a latch for DIN-rail at-
tachment.
Supply 24V operating voltage to terminals A1 (+) and A2 (-). Connect button (reset fault memory) to terminal A2.
Input circuit: DNDS 2C, 2D
- Proximity sensor (PNP):
Connect output of the first proximity sensor to IN1(IN3) and the 2nd to IN2 (IN4).
Both proximity sensors should be connected to supply voltage A1 and A2.
- Encoder with DNIA adaptor:
Connect output IA1 of the DNIA to terminal IN1 (IN3); connect output IA2 of the DNIA to terminal IN2 (IN4). A1
of both units should be connected together.
Programming
- Normal rpm setting: connect 24 VDC to the terminals D1-D3 (D4-D6) according to T1.
Input circuit: DNDS 2GA
Connect the equipment by using DNDA 15/8 or DNDA 25/8 adapter cables to the encoder.

Please note for operation
To prevent a welding together of the contacts, a fuse (6 A slow acting) must be connected before the output
contacts.
The total of the reaction times must not lead to a dangerous status.
Use copper wiring that will withstand 60/75° C.
Tighten screws to terminals with 0.8 Nm max.
Important details in the section "Technical Data" should be noted and adhered to.

Faults - Errors of DNDS 2C, 2D and 2GA

Welding of one contact makes it impossible for the other contact to be switched on.
LED "SPEED" and "STOP" do not light:
A PNP proximity sensor failure.
PNP proximity sensor not connected.
PNP proximity sensor is not installed on the tooth wheel.
There is a line break to the DNIA.
The encoder is not connected.
LED "SPEED" flashes green with 1 Hz interval, the sensor at input IN3 is defective or there is a line break at that
input, or Track A of the encoder 2 is missing, ELSE LED flashes red IN4 or Track B failure.
LED "STOP" flashes green with 1 Hz interval, the sensor at input IN1 is defective or there is a line break at that
input, or Track A of the encoder 1 is missing, ELSE LED flashes red IN2 or Track B failure.
To reset the error disconnect the operating voltage for at least 2s (disconnect A1)
LED "STOP" and LED "SPEED" flashes in 2 Hz intervals:
DNDS disturbance.
Error by improperly installed external signal lines.
The fault can possibly be eliminated by interruption of the operating voltage for at least 2s (disconnect A1).).
