To secure your controller to the DIN rail, pull the clip down, place it onto
the rail and gently push the clip up. To remove the ELCB, pull the
retaining clip down with a flat screwdriver and gently remove the ELCB
from DIN rail.
Wiring
1. Use 12-24 AWG single-core bare wire or multi-core (stranded) wire for
the I/O wiring. The ELCB terminal screws should be tightened to 3.80
kg-cm (3.30 in-lbs) using 60/75°C copper conductor only.
2. DO NOT wire empty terminals. DO NOT place input signal wires and
power wires in the same wiring circuit.
3. DO NOT drop tiny metallic conductors into the ELCB while installing the
controller or other equipment.
Power Supply
The input power supply for the ELCB-PB controller is AC. When operating
ELCB-PB, please note the following points:
1. The range of the input voltage should be 100 ~ 240VAC. The power
supply should be connected to L and N terminals. Please note: wiring
110VAC or 220VAC to a +24V output terminal or to digital inputs will
result in serious damage to the ELCB.
2. Use 1.6mm wire (or larger) for the grounding ELCB.
3. A power loss for less than 10ms will not affect the operation of the ELCB.
However, longer power loss or a sustained drop of power supply voltage
will stop the running of the ELCB, and all outputs will turn
“OFF”. When
proper power is restored, the ELCB will resume operation. (Please keep
this in mind when you use latched auxiliary relays and registers in your
ELCB program.)
4. Please refer to the electrical specification table for the maximum output
of the +24V power supply output terminal for each controller. DO NOT
connect other external power supplies to this terminal. Every input point
requires 5 to 7mA to drive when powered by rated voltage 24V to 30V
(i.e. 16 input points will require 80 to 112mA to drive). The +24V input on
ELCB-PB is only for digital input points; other external loads are not
supported.
Safety Wiring
In an ELCB control system, many devices are controlled at the same time,
and actions of any device could influence another device, i.e. breakdown of
any device may cause the breakdown of the entire control system.
Therefore, we suggest you wire a protection circuit at the power supply
input terminal. See the figure below.
