Shift Controls is committed to producing a product where safety is paramount. We realize safety directly corresponds to meticulous design, selecting the highest quality components, and demanding perfection in construction.
FRONT PANEL SAFE/RUN SWITCH
|A two-position RUN/SAFE selector switch allows an operator to place the temperature control panel in SAFE mode when not in use. This de-energizes the safety contactor and places the controller in a STOP mode.
SAFETY POWER CONTACTOR
|Power is physically disconnected from the heater by an electromechanical contactor when the following occurs:
• The SAFE/RUN Switch is placed in the SAFE positionThis feature ensures power is disconnected from the heater to protect personnel and equipment during a fault, over-temperature condition or when not in use.
• An over-temperature condition occurs (PV > ALARM Temp)
• A sensor fault occurs (ex. thermocouple becomes disconnected)
• The optional external interlock relay is de-energized
CURRENT-LIMITING MAIN BRANCH FUSING
|All panels feature current-limiting fusing which comply with main branch power distribution requirements. The current-limiting specification limits the energy released during an over-current condition and allows the panel to be rated with an industry leading Short Circuit Current Rating (SCCR) of 100 kA.
FINGER-SAFE (IP2X) CONSTRUCTION
|The interior of the panel is designed and constructed to be fully finger-safe (IP2X) which can reduce the risk of accidental contact with energized parts during OSHA and NFPA 70E allowable energized work.
QUALITY COMPONENTS AND CONSTRUCTION
|All components are manufactured by industry leading name brands and are UL Listed or UL Recognized. The panel design complies with or exceeds UL508A and NEC Electrical Codes. All wires and terminal blocks are clearly labeled and numbered according to the included detailed wiring diagrams. Control wiring is separated from the main power wiring, through fuse protection, reducing risk to the user and connected systems.
