Remove Voltage on Fault-
When the unit is in LATCH mode and a fault is detected, the relay will latch.
When Remove Voltage on Fault is selected, high voltage will be disabled while the relay is latched, so the
wire may be safely handled or inspected. When the system is reset either by pressing the front panel
reset button, connecting the RESET and GND terminals on the terminal block, or providing a remote reset
command through the Compact Comm modules, the system will be reset and high voltage will be
restored.
Remove Voltage on Fault
has no effect when the unit is in
Non-Latch
mode
Metal Contact
- Sometimes referred to as BARE WIRE. A Metal Contact fault is defined as a defect or bare
patch in the insulation that allows the electrode to come into momentary direct contact with the wire
conductor. In order for a fault to be typed as a metal contact, the bead chain electrode must make
physical contact with the conductor under test.
Multi-Pinhole-
A Multi-Pinhole is defined as two or more pinhole faults closely spaced. It can also be a
single fault of longer duration where no metal contact was made between the wire conductor and the
electrode.
Pinhole-
A pinhole is defined as a short-duration fault where no direct metal contact between the wire
conductor and the electrode is made.
Set Point Voltage-
This is the desired test voltage that is input through the front panel controls or remotely
by PLC
Voltage Watchdog-
Test Voltage parameters may be set by users to ensure that adequate test voltages
are always being used to test product. These values can be based off of upper/lower limits (WDL), or
percentage of set point voltage (EVP).
New Features
Display
:
The DC-B is available with a bright, detachable display, (Model RC). This display connects
to the test module with a short serial cable and eliminates the need for a separate remote display
(like our previous model ARC, used with the DC-xxA). The RC display can be mounted up to 60
meters (200 feet) away with a longer, shielded, serial cable. If the customer wants to mount the
RC display remotely in a rack mount instrument panel, a rack-mount adaptor is available, (CIC
Part No.
92244
).
Front Panel Security
: The DC-B system offers a customizable password protect option that can
be enabled, if desired, to prevent operators from changing or accessing information. There are
four levels of password protection that allow supervisors to choose exactly what the operators
are able to access.
BD-12S Design (Patent Pending)
: The new split-electrode design provides an easy way to string
up a cable through the bead chain electrode, guaranteeing precise center placement for the most
effective and reliable test. The bead chains are now arranged at an angle, eliminating gaps
between hanging beads, and providing the best coverage around the product at all times.
