CED-L

CED-L

External display with integrated overload control unit

CED-L combines a large external display and a complete overload limiter in one IP54 aluminium enclosure. The integrated control unit monitors up to two load cells, limits the load with pre-alarm and alarm thresholds and shows the load in large 3" or 4" LED digits that are clearly visible to the operator and the site.

Overview

Load limitation is performed via a safety relay with guided contacts monitored in real time, with a dual-channel input system for double-bridge load cells in accordance with Category 2 as per EN 13849-1, PL d.

Key Features

Display & Operation

6-digit LED display with 3" (76 mm) or 4" (102 mm) character height
IP54 aluminium profile enclosure with plexiglass front panel
CED-3X: 620 × 150 × 100 mm • CED-4X: 770 × 150 × 100 mm
LED indicators showing relay output status; 5-key keypad
RS485/RS232 serial ports for continuous one-way ASCII transmission

Integrated Control Unit (L)

Dual-channel input system for double-bridge load cells (Cat. 2, EN 13849-1, PL d)
Load limitation via safety relay with guided contacts, monitored in real time
Independent general alarm relay
2 relays for general threshold intervention (e.g. pre-alarm / discharge system)
3 changeover relay outputs (standard) or 4 relays incl. one safety relay (option)
2 independent load cell inputs; alarm on load cell connection failure

Load Limiting

Load limitation by alarm and pre-alarm thresholds
Single and summed load limitation for systems with up to 2 weighing points by connecting multiple units
Lifting operation counters
When the load is below the set nominal value, the 3rd and 4th relays enable operation at the 3rd and 4th speed levels

Main Functions

Connection to PC/PLC via RS485/RS232
Connection to a remote display via RS485/RS232
Up to 2 load cells in parallel via junction box
Connection to other units for the summing function via RS485 or RF (option on request)
Continuous load cell connection integrity check
Digital filter to reduce the effects of load oscillation
Theoretical calibration (via keypad) and real calibration (with sample weights)
Tare weight zero setting
Automatic zero setting at power-on
Gross weight zero tracking
