Important Notes
2.3 Transport and Storage
If the control monitor is to be transported or stored for a
lengthy period of time, the following safety precautions
must be taken:
• The temperature must remain within the range
–10°C to 70 °C.
• BNC connections must be covered with a non-shortcircuiting
cover.
• Make sure that no dirt enters the control monitor.
• The environment should be as dry as possible and free
from vibrations.
• Make sure that the control monitor is placed in a position
where no pressure can be exerted upon it.
• As long as the control monitor remains unused, it
should always be stored in its original packaging.
2.4 Supply Voltage
The control monitor is designed for a voltage range from
18 ... 30 V d.c (24 V d.c). Protective diodes against wrong
polarity are included to prevent damage to the control
monitor. It has a self-recovery thermal cut-out (>0.5 A),
which interrupts the current in the event of an overload. To
ensure that the cut-out will reset, the current must be interrupted
entirely for several minutes.
2.5 Electromagnetic Compatibility (EMC)
The control monitor has CE conformity and complies with
the EMC standards EN 61000-6-3 (interference emission,
residential area) and EN 61000-6-2 (interference immunity,
industrial area). The interference immunity test was carried
out with a ground screw connected. Inputs and outputs are
protected against electrostatic discharges by varistors.
In the tests carried out in this connection, the signal ground
was connected to the equipment case. This connection is
provided as standard and uses the M2,5x5 connecting
screw at the front of the case. The user can remove this
connection at any time to eliminate ground loops by removing
the screw. The common-mode voltage must not
exceed ±40 V.
