1 How to use this Manual 1.
2 LON module overview 2.1 General description The LONMark® certified SED2 LON module provides direct digital control of SED2 Variable Speed Drives (VSDs). The SED2 can reside on a LONWorks® network, enabling information sharing with all other LONMark products from multiple vendors. The SED2 LON module is LONMark-compliant with Variable Speed Motor Drive Functional Profile Number 6010.
2.3 Network Variable Types and Config. Properties The LON module communicates with the LONWorks network using real units in the form of Standard Network Variable Types (SNVTs) and Standard Configuration Property Types (SCPTs). Figure 5193B02 provides a summary of the LON module network variables and configuration properties.
2.4 Network Variables for Object 0 (node object) Network Variable Input or output Units of measurement Description nviRequest Input Object request nvoStatus Output Object status 2.

2.7 Standard Configuration Property Type (SCPTs) The following SCPTs are network configuration property inputs (nci).
3 Installation and wiring 3.1 With SED2 frame sizes A…C IP20 WARNING: Make sure that the VSD is deenergized (off) before you install or remove the LON module. Remove the SED2 operator panel and the terminal cover of the I/O module. 5192J16 1. 1 2 5192J09 2. Install the LON module on the SED2 I/O module by inserting the two bottom guides into the appropriate slots at the sides of the I/O module and pushing the upper section inward until the locking mechanism latches (Figure 5193J01).
3.2 Installation in SED2 frame sizes D…F IP20 WARNING: Make sure that the VSD is deenergized (off) before you install or remove the LON module. For frame sizes D, E, and F, the LON module mounts inside the VSD housing. 1. Remove the operator panel, lower and upper front cover. See drawing 5193J03 below. 6. Terminate end of network cable with a single, two-pin, female LONWorks FTT-10A connector. 2.
3.3 Installation in SED2 frame sizes B…F IP54 WARNING: Make sure that the VSD is deenergized before you install or remove the LON module. 1. Loosen the door fixing screws on the front of the IP54 housing and open the door. 2. Remove the operator panel extension module (with ribbon cable) from the EI/A module by pushing the lever above the extension module upward and, at the same time, pulling the extension module downward. NOTE: Do not disconnect the ribbon cable. 3.
3.4 Installation and wiring notes WARNING: A VSD can be switched on unintentionally if the serial bus installation is not operated correctly. The bus must be started by personnel who are qualified and trained in installing systems of this type. 1. DIP switches Leave the DIP switches on the front of the LON module in OFF position (factory setting) to ensure proper operation of the LON module. 2. Wiring Wiring must conform to local codes and ordinances. 3. Wire routing • Maintain a minimum of 1.

4 Startup procedures 4.1 Setting Up SED2 parameters See SED2 Getting Started Guide, document no. CM1G5192en for procedures to commission and start up the VSD. The following table lists the SED2 parameter settings that are required for correct communications and control of the VSD with a LON module. CAUTION: Changes made to the parameters other than what is listed in the table below can result in damaging the VSD or building equipment. 4.1.
4.2 Verifying parameter operations After setting VSD parameters, perform the following steps to verify parameter operations using the drive keypad: Step Press 1 2 Displays r0000 and 3 4 Enables scrolling to the appropriate parameter number Displays the value of the selected parameter and Enables scrolling to the appropriate parameter value Confirms parameter value setting and enables scrolling to other parameter numbers 5 6 Action and then Returns to the display readout when finished 4.
5 Application note using LG-Ni 1000 sensor example Use the following parameter settings for PID loop control via the LON module. Parameter and setting Value of parameter Explanation of value P2201, set to appropriate setting for your installation. Fixed PID setpoint in °C P2253[0], set to one of the following: • 755[0] for analog input 1 on the drive Selection of setpoint source LON-mapped setpoint P0701[0], set to 16.
5.1 Turn-around binding When using an analog value (e.g. from the LG-Ni 1000 temperature sensor), the measured value is per default downloaded to the nvoEffectlAQ variable. To place the measured value on the nvoTemp variable, a turn-around binding must be applied.
Output rates bidirectional and configurable transmission rates for output network variables height: 161 mm (6-11/32 in.) width: 73 mm (2-7/8 in.) depth: 43.5 mm (1-23/32 in.
7 WARNING: Troubleshooting Make sure that the VSD is deenergized (off) before you install or remove the LON module. 7.1 Status LED functionality A tri-color LED provides indication of current LON module operating status and error conditions, such as if more than one SNVT is bound by LONWorks. The following table describes the LED indication. Status LED indication LED Color & State Dark No power is supplied Red, flashing A hardware fault or software error has occurred.
