1. Short description

The electronic reversing load relays with motor management (ELR-MM) are a
combination of fast, wear-free electronic reversing load relays (with complete locking
circuit and load wiring) and the latest measurement and evaluation electronics. Triggered
with a low capacity, they can keep the capacity of approx. 4 kW on the load side within
well-measured limits.

Power with limits
Monitoring is accomplished by freely parameterizable switching and message thresholds
for overload and underload detection. The default setting of the thresholds for both
directions of rotation is identical, or separate for clockwise/anticlockwise rotation.
The basis value for parameterization is the consumed effective power (calculated with
three currents, voltages and the phase angle!), thus offering a much more precise basis,
independent from voltage fluctuations and drive load, than when merely the current is
taken into consideration. If a switching threshold is exceeded or fallen below, ELR-MM
immediately (or delayed with adjustable "Delay Time") initiates an emergency shutdown
of the motor. Additionally a message – for example to a subordinate control station – is
transmitted via an output.
This state can only be deactivated via a defined reset. If the quantity of effective power
taken up is registered as being above or below the message thresholds, a check-back
with just the duration for which the module was addressed is returned.
Signals are also generated by the module to recognize the direction of rotation. Phase
failures are detected and signalized.
Permanent status monitoring with high scanning rates, and the fast semiconductor switch,
make protection of the entire system possible, including motor protection.
Without any extra wiring – with just one single device – pumps, actuators, fans and tools
are monitored with respect to function, contamination (filter or similar) and wear. The
adjustable "Inrush Suppression" time can be used to mask out the switching operation
from the monitoring process.

2. Notes on connecting

2.1. Mains connection and line protection
Attention: Never carry out work on live parts!
• When connecting the 3-phase network, it is essential to observe the terminal
identification on the upper side of the housing! Connecting a phase to the neutral
terminal block "N" results in the equipment being destroyed!
Fig. 1
• In accordance with VDE 0100 and VDE 0636, connecting the electronic load relay to the
3-phase network requires a conductor cross section of 1.5 mm
supplied with one fuse (10 A slow-blow) each.
• The operating voltage and control voltage inputs must be operated with power supply
modules acc. to DIN 19240 (max. 5 % residual ripple)!
• In order to avoid the inductive or capacitive decoupling of interfering impulses with long
control lines, we recommend the use of shielded conductors.
