Rear Panel Terminals

Note regarding Rate signal input and Count signal input:

The 2000CT is designed to accept a rate signal input and/or a count signal input and these can be supplied by two

different sensors or pulse sources. If only one signal source is to be used for both Rate and Count monitoring, then

simply connect the signal source to IPa (terminal 10) and fit a link from IPa to IPb (terminal 12).

Sensitivity Control

This is located to the right of the terminal block on the rear panel and is factory pre-set. However,
should it be necessary during on-site installation, adjustment is accessible through a hole in the rear
panel itself.

Maximum sensitivity is obtained when the Control is turned fully clockwise. It is recommended that
the sensitivity level is increased only as far as necessary to obtain a steady signal. This minimises
the risk of detecting spurious signals.

Alarm Outputs

The Alarm Output facility is available in the

RATE

mode only. The

HIGH

alarm will be activated when

the value shown on the display is equal to, or greater than, the value programmed into memory. The

LOW

alarm operates on a value equal to, or below, the programmed value.

The alarm outputs automatically reset when the value shown on the display returns to a “no alarm”
value.

Mains Earth

2000CT Counter/Tachometers

are supplied with a three core mains cable. The earth lead from this

cable is connected to terminal 4 ( ) on the Rear Panel terminal block. For most applications this
Earth terminal should be linked to 0V terminal 3 (COMMON) - see also

Safety Information for EU

Electromagnetic Precautions

Exceptions to this are if the COMMON is connected to Earth elsewhere in the system (care must be
taken to avoid Earth loops); or it is found that the mains earth is of poor quality; or when it is essential
that the signal input or the analogue output of the instrument is floating.
