• Microprocessor compact controller-unit with LED-display and bargraphs • Automatic self-tuning - adapts to different controlled systems • Bargraph indicates the control deviation • Integrated current-transformer • Flexible softstart-routine • Various self-monitoring features (with additional alarm unit) This temperature-controller plug-in unit was specially designed to fit the demands of the plastic molding industry. It comes up with a clear design and establishes easy operation and various self-monitoring features. The unit is inserted in multi-zone mainframes, which are used to control hotrunners, presses and extruders. Control-electronics with integrated solid-state relay in a compact plug-in unit complying with 19“-rack-standards 3HE/10TE, pin-compatible with controller-unit-type 3080TPS, operated in mainframes RG225 ... RG3060 (2... 3o zones). Microprocessor-controller with automatic self-tuning establishes best control-results for fast nozzles as well as for slow manifolds or extruders. During normal operation the actual tempera-ture value is displayed on the 3-digit LED-display. The 10-digit, 3-color (gn/y/r) bargraph above the display indicates the control deviation in a +/-16K-logarith-mically scaled range. Pushing the UP/DOWN-buttons switches the display to setpoint value. Possible changes can be confirmed by pressing the mode-button, after 20sec. they are accepted automatically. Process-high/-low-limits can be set between +/-3 ... 99K. When passing a limit the corresponding red LED flashes and the relay-exit switches-over. Sensor-breakage is signalled by a flashing red LED. The controller switches over to manual power-control and effects the last used power setpoint, which may be adjusted at any time. Manual power-control is possible even whilest sensor is working properly. For further protection of sensitive heating-elements the assigned power can be permanently limited to 60%. The corresponding LED indicates that power-limitation is active. During softstart the controller-unit works with reduced setpoint temperature 80°C for 5min (factory preset). Cold heaters are slowly pre-heated, moisture is expelled. The NL 3070 THD temperature-controller-unit features a facility to override the normal setpoint temperature with 1 - 9K at the first heating-up. This intended overshooting shortens the required time to „melt“ frozen injectors. As soon as the increased boost- temperature has been reached, the unit immediately reduces the temperature to the normal setpoint and thus ends the boost-routine.

Open the catalog to page 1Load-current monitor Load-current is permanently displayed on a 10-digit bargraph. The exact current can be shown on the multi-purpose-display. Load-breakage is additionally indicated with a flashing red LED. The control-unit is provided with a signal-port to activate the standby-routine by the signal/alarm plug-in-unit NL 3053SX. The standby-value effects the temperature-termination to a defined percentage of the desired temperature. The standby-routine permits a reduction of the desired temperature of all heating-zones in a unit simultaneously. This way mass variations as a consequence of long-term...
