- VOLTAGE DETECTOR TO PREVENT ARC-FLASH HAZARDS
- PREVENTION OF ELECTRIC SHOCKS
The Voltage Detector JSC-88A offers a ZERO-TOLERANCE SOLUTION
for safe electrical shutdowns and thus preventing electrocutions
or electric shocks. Thanks to the Voltage Detector JSC-88A,
the maintenance staff can now proceed safely to maintenance
work without the threat of electrical shocks or arc-flashes.
This is then a major step towards preventing arc-flash hazards
and electrical shocks during maintenance works.
The
JSC88A is designed for either Solidly Grounded or High-Resistance
Grounded Electrical systems; It offers a Zero-Tolerance Solution
for Safe Electrical Shutdowns for Electrical related, Mechanical
related or Operational related type of jobs.
This
model won't work on Floating Electrical Systems.
The
JSC88K6 is designed for Floating Electrical Systems; It offers
a way to perform Safe Electrical Shutdowns for Mechanical
related or Operational related type of jobs where electric
parts are not involved, where you only want to make sure that
a given electric equipment will not start-up inadvertently
while under mechanical or operational maintenance; the JSC88K6
works on floating systems and it will only indicate if more
than one phase are still active. Since motors cannot start-up
with only one single phase active, the JSC88K6 can help perform
safe shutdown for mechanical or operational type of jobs where
electrics is not involved.
The Voltage Detector JSC-88A or JSC88K6 is designed to be
permanently installed on the door of any disconnect-switch,
starter panel or MCC. The voltage Detector JSC-88A or JSC88K6
can be safely operated by qualified operators in two (2) easy
steps:
Step #1:
While the disconnecting device is still in the 'ON' position,
the qualified operator must make sure that the three (3) JSC-88A
or JSC88K6 LEDs are 'ON' (or lit), indicating that the Voltage
Detector JSC-88A is working properly and that the voltage
is normally present on the load-side of the switch, which
is normal at this stage.
If (and
only if) all the 3 LEDs are ON (or lit) in STEP-1, you can
proceed to step #2
If
any of the LEDs are not lit at this stage, STOP ! An
authorized qualified staff member should investigate the problem
and take appropriate corrective action before you can proceed
with STEP #1 again.
Step #2:
As soon as the disconnect-switch has been switched to the
'OFF' position, the qualified operator must carefully observe
the Voltage Detector JSC-88A or JSC88K6 again and make sure
that the three(3) LEDs are now 'OFF' (i.e. not lit) indicating
that voltage is no longer present on the load-side of the
switch.
If
(and only if) all 3 LEDs are OFF (not lit) at Step #2, there
is now no more remaining voltage on the load-side of the switch.
If
the Voltage Detector JSC-88A or JSC88K6 detects any remaining
voltage on the load-side of the switch, one or more LEDs will
remain 'ON' (or lit). This would indicate the presence of
voltage on the load-side of the switch, thus a serious electrical
hazard. STOP ! An authorized qualified staff member should
investigate the problem and take appropriate corrective action
before proceeding with STEP #1 again.
