IMPORTANT SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS BEFORE USING THE iPAK2
WARNING
DO NOT DISASSEMBLE, REPAIR, OR MODIFY THE iPAK2. These actions can cause electric shock and fire.
Use only as described in this manual. Use only BF ENTRON recommended accessories and
replacement parts.
Stop operation if any problems occur. If the equipment is not working as it should, has been dropped,
damaged, left outdoors, or been in contact with water, contact BF ENTRON.
Only apply the specified power. Application of a voltage or current beyond the specified range can
cause electric shock or fire.
Do not use damaged plugs or connecting cables.
Keep water and water containers away from the iPAK2. Water ingress can cause a short circuit, electric
shock, or fire.
Do not insert objects into openings. Do not use with any opening blocked; keep free of dust and debris.
Do not install the iPAK2 in any of the following environments
o damp environments where humidity is 90% or higher.
o dusty environments.
o environments where chemicals are handled.
o environments near a high-frequency noise source.
o hot or cold environments where temperatures are above 40°C or below 0°C, or environments
where water will condense.

Introduction
The iPAK2 controller is suitable for MFDC spot, projection, roll-spot, seam and multi-welding welding
applications.
The controller supports:
pre-heat, main heat and post-heat intervals
force profiles
multi-gun, multi-air valve applications
multiple electrodes
The iPAK2 has multiple communication and control options and can be configured by a number of
programming options. The Ethernet port supports simultaneous programming and control via a single
physical cable.
Short-circuit proof outputs and a guided-contact pilot relay provides enhanced safety. Connection to the
power system is via a single ribbon cable. Analog inputs and outputs can be used to drive a proportional
air regulator valve for force control.
Operation in Standard mode provides a basic set of features for simple applications. Extended mode
adds advanced features for more demanding applications. Choose between Standard or Extended
features (Section 12 Configuration). The iPAK2 must be restarted after changing this setting.

Programming options
1.NetFlash
This PC-compatible program displays and allows editing of all
welding parameters and status information.
In addition to programming, NetFlash provides backup/restore
functions for control data, live data logging to a file and a utility for
updating the firmware in the iPAK2.
2. WSP3 Pendant
iPAK2 series controls work with the same WSP3 pendant that is
used with EN7000, WS2003 and iPAK (v1). Access to all
parameters is provided, plus diagnostic indication.
3. MODBUS
A PLC or HMI MODBUS master can be used to program, control
and monitor an iPAK2. All parameters are directly mapped to
MODBUS registers for easy access. Both MODBUS-TCP/IP
(Ethernet) and MODBUS-RTU (RS485) protocols are supported.
4. Ethernet/IP
An optional adapter card can be fitted to the expansion port,
providing full data access via the EtherNet/IP protocol.
