: 2.69e-8 fits

: 94.23%

: 188683 hours #  21.5 years

: 230700 hours #  26.0 years

: 1036000 hours # 118 years

Life duration for the system is 20 years. During this period the data integrity of the programable devices are garanted, this time

is equivalent to the MTBF of the channel. After this period the overspeed protection system must be replaced.

6.2 Special specifications :

6.2.1 CSA specifications

• Pollution Degree 2 environment

• Installation Category II

• Altitude : sea level

• Humidity : 0%...90% condensation to be avoided

• Electrical supply 24 Vdc, max. 8A, Double or Reinforced insulated from mains

• The Ft3000 rack system must be installed in a indoor environment.

• Operating temp -5...+40ºC

Reference conditions: Operating temperature +20ºC

Supply within defined limits

Smallest measuring range:   0...1.000 Hz

Largest measuring range:   0...35.00 KHz

Once the machine factor M is defined (M = Freq. In Hz/ measured value eg rpm), the input of  measuring range and limit

values is directly in the chosen physical units eg rpm. In place of the machine factor, the number of pulses per rev from the

pole wheel may be entered. Moreover once the nominalspeed is defined (=100%), limits can be given as a percentage of

nominal. The measured range may be continuously exceeded up to 55KHz without affecting functionality or causing any

damage to the unit.

Sensor signal input-

Frequency input 1

Input card -0X for frequency input 1. plugged onto the motherboard FTFU 3024

Input card E-01:

potential free, isolation 500V, 50Hz,1 Min. from electronics and earth ie from front panel

and card frames.

for connection of electromagnetic, ferrostat or HF sensors, proximity switches and sensors

with line amplifiers.

Input impedance:   100kohm

Input voltage:               50mV...80V rms

Bandwith  (-3dB)    : 0.5 Hz /3.3 kHz

Frequency domain for pulsed signals   : 0.02Hz / 30kHz

Input level for sinus signals    : 50 mv rms at min trigger

Input level for pulsed signals    : 10Vpp at 20% trigger  level

Trigger level:               adjustable between 0 and +3.5V via front panel

trimmer T. The voltage at test point T to ground of

fixed hysteresis of 50mV rms = 141mVss

Integral pull up (+12V) and pull down (0V) resistance of  11 kOhm for connecting 2 wire

sensors, jumper selectable.

Sensor monitoring of 2 and 3 wire sensors, jumper selectable -If the supply current is

< I min or > I max a defect is signalled by the green LED ‘MO’ off and the red LED ‘MO’

on.

I min is set via front panel trimmer ‘L’

I max is set via front panel trimmer ‘H’

A voltage at test points ‘L’ and ‘H’ to ground from 0...10V corresponds to supply current of

0...30mA.

A voltage from 0...10V at test point ‘M’ corresponds to the actual supply current of  ...30mA.

To adjust the trimmers the module must be plugged onto an extension card to open the seal.

Integral sensor supply of +11.5...12.5V, max 25mA, short circuit proof  (max 40mA).
