When it is time for maintenance and you open the disconnect switch or

breakers, ARE YOU 100% SURE THAT NO VOLTAGE IS PRESENT ?

One of the hazards of today’s plants is working on three-phase

systems. Why is this a hazard ? Because it is difficult to be absolutely

certain that the power is truly « OFF » once the disconnect switch or

breaker has been opened.

HUMAN ERRORS & HAZARDOUS ENVIRONMENTS

Accidents happen … mostly due to human error:

Incorrect measurement setup

Incorrect readings

Lapse of concentration

Accidents also happen due to hazards in the environment:

Carbon deposits (providing electrical path for the current)

Defective voltmeter or accessories

Sticking switch blades

Dual sourcing

Defective electronic breakers which are difficult to diagnose

Any other hazardous situation that allows for conduction after the

breaker or disconnect-switch has been opened

The JSC-88 or JSC-88A helps to prevent accidents

We can now help to prevent electrocutions in the work place, thanks to

the JSC-88 or JSC-88A Voltage Monitor.

The JSC family, thanks to its small size and light socket mounting

design, is easy and quick to install on the door of any starter panel.

Originally developed for Alcan (the well-known International Aluminium

Smelting Company), this voltage monitor has been in large scale use

since 1988 in a number of international industrial environments.

How to use the JSC-88 or JSC-88A … in two easy steps

To use the JSC familly properly, the following steps must be followed

carefully:

STEP #1- While the breakers are still in the « ON » position, make sure

that the three (3) LEDs on the JSC-88 or JSC-88A are « ON » (or lit),

indicating that our voltage detector is working properly and that voltage

is present downstream of the breakers.

Important note : If any of the LEDs is not lit at this stage, an authorized

staff member should investigate the problem and take appropriate

corrective action before proceeding with STEP #1 again.

STEP #2- As soon as the breakers have been switched to the « OFF »

(or Zero Energy) position, examine the JSC-88 or JSC-88A again and

make sure the three(3) LEDs are now « OFF », (i.e. not lit) indicating

that voltage is no longer present downstream of the breakers.

Important note : One or more of the LEDs will remain « ON » if the

JSC-88 or JSC-88A detects any voltage. This would indicate a serious

electrical hazard. An authorized staff member should investigate the

problem and take appropriate corrective action before maintenance

work proceeds.

Note: There is no direct association between a specific led and a given

phase. The JSC-88 or JSC-88A haven’t been conceived for detecting

a phase loss but the presence or not of voltage in industrial

environment.

The JSC-88 or JSC-88A is a very reliable detection unit designed to

indicate visually whether, or not, the voltage on a given system is at

«Zero Energy». It drastically improves the security for maintenance

teams working on three-phase systems. As long as voltage is present

downstream of the breakers, the JSC-88 or JSC-88A LEDs will remain

lit, allowing for a rapid visual inspection for the presence or absence of

hazardous voltages. The use of the optional KLQ-Kit (only with the

JSC-88A) gives an additional security by providing a visual indication

at the motor site.

Do you have a question about the CONTROLAB JSC-88 and is the answer not in the manual?

The VOLTAGE DETECTOR JSC-88 or JSC-88A is a highly reliable, robust, and easy-to-install device designed for zero-tolerance solutions to prevent electric shocks in industrial environments. It provides a visual indication of current leakage, ensuring safety and facilitating maintenance.

Function Description

The JSC-88 or JSC-88A acts as a voltage detector that monitors three-phase electrical systems for current leakage. It is designed to detect any current leakage greater than 2mA, providing an immediate visual alert through its luminescent LEDs (special low-current LEDs). This allows for continuous monitoring of the electrical system's integrity, helping to prevent electric shocks and ensure worker safety.

The device is particularly useful in environments where human interaction with electrical systems is frequent, such as motor control centers (MCCs). By providing clear visual indications, it helps identify potential hazards before they escalate, thus reducing the risk of accidents and ensuring compliance with safety standards.

Important Technical Specifications

Operating Voltage: The JSC-88 or JSC-88A comes with a universal voltage reduction kit, allowing operation from 208 volts to 600 volts.
Current Consumption: Maximum current consumption is 1.9 mA, making it an energy-efficient device.
Sensitivity: Capable of detecting and indicating any current leakage greater than 2mA.
Dimensions: The device measures 72mm x 51mm x 26mm (2.83" x 2" x 1").
Enclosure: Encased in epoxy, providing 100% resistance to hostile, humid, and dusty environments.
Certifications: UL (c us) and CSA certified, meeting NEMA-4X certification standards.
Visual Indicator: High luminescent visual indicators (special low-current LEDs) ensure readings are not affected by ambient light, allowing visibility regardless of placement on the MCC.
Wiring: It is recommended to use shielded wiring for the installation of the optional remote light kit (KLQ-Kit).
Connection: For proper and safe operation, the JSC-88A requires a link to neutral (or ground where permitted). For true floating systems, the JSC-88 should be used.
Ordering Information:
- JSC88A: Standard unit for 208 volts with KA reducer kit.
- KA: Voltage reducer kit (208 to 600 volts) for JSC-88A.
- KLQ-Kit: Optional remote light kit only with JSC-88A.
- JSC-88: Standard unit for 208 volts with K6 reducer kit.

Family Discounts: For large-scale deployments, such as those in Zero Energy, the JSC-88/JSC-88A LEDs remain lit, allowing for rapid visual inspection for the presence or absence of hazardous current. This feature significantly reduces the time required for safety checks.
JSC Family Integration: The device is part of the JSC family, which includes small-size and light socket mounting designs, making it easy to install on the door of any starter panel. Originally developed for Alcoa (the world's second-largest aluminum smelting company), this voltage monitor has been in large-scale use since 1988 in a number of international industrial environments.

Maintenance Features

Simplified Troubleshooting: The visual indicators (LEDs) on the JSC-88 or JSC-88A provide immediate feedback on the status of the electrical system. If the LEDs are ON, it indicates the presence of hazardous current, prompting immediate action. If the LEDs are OFF, it suggests a safe condition.
Proactive Maintenance: The device facilitates proactive maintenance by allowing personnel to quickly identify and address potential electrical hazards before they lead to equipment failure or accidents. This helps reduce downtime and maintenance costs.
Regular Checks: It is recommended to perform regular checks (e.g., every 100 hours or once a month) to ensure the device is functioning correctly. This involves verifying the LEDs and, if necessary, performing a controlled test with a current leakage to confirm its sensitivity.
Systematic Approach to Troubleshooting:
- Step #1: Confirm that the three (3) LEDs on the JSC-88 or JSC-88A are "ON" or "OFF." "ON" indicates hazardous current, while "OFF" indicates a safe condition.
- Step #2: If any of the LEDs are not lit at this stage, an authorized staff member should investigate the problem and take appropriate corrective action before proceeding with Step #1 again.
- Step #3: As soon as the breakers have been switched to the "OFF" (or Zero Energy) position, examine the JSC-88 or JSC-88A again and make sure the three (3) LEDs are now "OFF." This is vital for indicating that voltage is no longer present downstream of the breakers.
Important Note for Maintenance: One or more of the LEDs will remain "ON" if the JSC-88 or JSC-88A detects any voltage. This would indicate a serious electrical hazard. An authorized staff member should investigate the problem and take appropriate corrective action before maintenance work proceeds.
No Direct Association with Specific Failures: The JSC-88 or JSC-88A haven't been conceived for detecting a phase loss but the presence or not of voltage in industrial environment.
Prevention of Accidents: The device helps prevent accidents in the workplace by providing continuous monitoring and immediate alerts, ensuring a safer working environment for personnel. It is particularly effective in preventing "human errors" such as incorrect measurements, missed readings, or lapses of concentration, which can lead to serious incidents.
