Product Description
PCS Company’s Nozzle Leak Detector is a unique device that detects plastic leakage between the mold and
the machine nozzle which could be caused by cracked nozzle tips, misaligned nozzles, plugged gates, etc. The
Nozzle Leak Detector provides a 90 dBA audible alarm plus a visual alarm light. Using the input and output
receptacles, interface with the press to stop the molding cycle to eliminate costly downtime and equipment
repairs.
Installation
1. Lock & tag out incoming power for the machine to be modified.
2. Attach Thermocouple Mounting Bracket Assembly to the nozzle with a hose clamp (sold
separately) over the heater band or directly on the nozzle OD if using an internally heated
nozzle. Adjust the thermocouple in the bracket so the tip of the thermocouple is just behind the
hex portion of the nozzle tip and tighten in place with set screw in the bracket.
3. Plug thermocouple into the thermocouple socket located on the right side of the unit.
4. Plug the leak detector unit into a standard 120V grounded receptacle.
5. Adjust the set point on the controller to approximately 100 to 150°F below the nozzle zone
temperature.
6. To adjust the set point temperature on the controller, refer to the Model 3300 Controller
instruction manual.
7. When a leak is detected, the audible alarm will sound and the LED will light up. Turn unit OFF
and repair leak.
8. After the leak is fixed and the controller is reset, turn unit back ON. The audible alarm will
remain silent and the LED warning light will remain off until another leak is detected.
9. To interface with machine, wire the plugs (included with unit) to use for input and output to
your machines purge guard circuit or control panel. This interface will stop injection immediately
thus stopping the leak.
10. Insert plugs from machine into appropriate receptacles located on side of unit.

button will change the temperature continuously • Quickly pressing the Up and Down button while
holding the “*” button will change the temperature in 1-degree increments with each press.
3. After you reach the desired set point temperature (approximately 100-150 degrees below nozzle
temperature set point), release the “*” button; your set point temperature is now programmed. Note:
The current thermocouple temperature is displayed.
To Reset Controller:
1. After the unit detects a leak, the audible alarm and LED will activate and remain on until the controller
