Chapter 9 – Communications Chapter 9 — SED2 Communications Overview The SED2 drives are a family of inverters that are built, sold, and serviced by Siemens Building Technologies, Inc.- Adjustable Frequency Drives Group (SBT-Drives). Siemens Building Technologies has a Protocol 1 (P1) communication driver, FLN connection, and point database that is built into their drives and allows them to coexist on an APOGEE network with other floor level network (FLN) devices.
SED2 Operation & Maintenance Manual RS-232 Personal computers use the RS-232 standard for interfacing to a peripheral. When fully implemented, it uses many interconnecting wires and protocols to exchange data. In its most simple form, it consists of three wires: transmit, Tx; receive, Rx; and ground, GND. It allows communications between two machines only over a short distance. The Tx line of one machine connects to the Rx of another, and vice-versa. Voltage levels are typically +/- 12V.
Chapter 9 – Communications Point Database Table 8 provides point database information for Application 2722. For complete descriptions of these points, see other sections of this Users Manual and the Parameter List. For more information on installation, start-up, and programming, see other sections in this manual. Ordering Notes All SED2 drives come standard with FLN (P1) integration available and no additional parts are required.
SED2 Operation & Maintenance Manual Verifying Parameters After the SED2 setup, verify the parameters by performing the following steps using the drive keypad: 1. Press P. 2. r0000 should display. Use and to scroll to the appropriate parameter. 3. Press P to view the value of the parameter. 4. Use and to scroll to the appropriate value for the parameter. 5. Return to the display readout by pressing Fn and then P.
Chapter 9 – Communications Additional display points on the SED2 drive that may be of use: • INVERTER VER (Point 83); the SED2 firmware version number • DRIVEMODEL (Point 84); the STB drive model number Supervisory Control – This is the most typical application. The sensor for the control variable (water temperature) is hard-wired to the SED2 and the built-in SED2 control loop (PI loop macro must be enabled during drive setup) modulates the control device (fan).
SED2 Operation & Maintenance Manual Slaving the Drive CAUTION: This strategy is not normally recommended because you are using the network communications to close the loop. Delays due to network traffic can cause control to be degraded or lost, and depending on the setup of the drive, if there is a problem with the network, the drive may cause physical damage to the HVAC system by winding up to its maximum or dropping off to its minimum speed.
Chapter 9 – Communications Analog Inputs – Use ANALOG IN 1 (Point 45) and Analog IN 2 (Point 46) to monitor the status of the drives analog inputs (4 to 20 mA) from the field panel. For example, the chilled water feedback could be sent to the field panel, calculations performed, and the chilled water valve control command could be sent from the field panel through the drive and control the drive analog output over ANALOG OUT 1 (Point 47).

Chapter 2 – Electrical Installation Chapter 2 - Electrical Installation EMC-Compatibility NOTE: The Siemens Building Technologies SED2 Variable Frequency Drives are shipped without EMC line filters. (The EMC filter is most commonly used in Europe.) Where local codes or customer/installation requirements dictate, separately orderable line filters are available. More stringent Class B line filters are also available for most models.
SED2 Operation & Maintenance Manual Addendum Check that the contactors in the control cabinet are suppressed, either with RC circuits for AC contactors or flywheel diodes for DC contactors. In both cases, mount the suppressors to the coils. Varistor surge voltage protectors are also effective. This is important when the SED2 relay controls the contactors. 5191Z01 • Figure 2.

Chapter 2 – Electrical Installation Operation with a Residual Current Device (RCD) If a residual current device (also called a GLCI or RCCB) is connected, the SED2 operates with no interruptions under the following conditions: • A RCD, Type B is used. • The RCD must have a threshold current of 300 mA. • The neutral conductor in the system must be grounded. • Each RCD supplies only one SED2 (an no other loads).
SED2 Operation & Maintenance Manual Addendum Chapter 3 - Programming Bypassing the SED2 There are applications demanding maximum motor output. Additionally, there are applications requiring a SED2 bypass system for safety reasons. For these cases, the SED2 has an integrated bypass function. Parameter setup for bypass function (commissioning) Mains supply SED2 P1260, Source of changeover control Defines the possible sources for changing over to bypass/contactor operating mode.
Chapter 3 – Programming P1262, Bypass dead time Time delay between switching contactors (SED2 to bypass/contactor and vice versa) to allow motor to demagnetize (Figure 11). Setting range: 0 to 20 s Recommended setting: 1 second (default) P1263, De-bypass time Defines the time before a request to switch from bypass/contactor to SED2 is executed (Figure 11). Setting range: 0 to 300 second Recommended setting: 1 second (default).
SED2 Operation & Maintenance Manual Addendum Hibernation Mode If the SED2 reaches the hibernation setpoint in PID operating mode, the P2391 hibernation timer starts. After the timer expires, the SED2 drives the output frequency of the ramp to 0 Hz. T1 Hibernation frequency reached. Start of hibernation timer. T2 Minimum output frequency reached. T3 Output frequency decreased according to the set ramp. PID control of the output frequency is interrupted. T4 Output frequency = zero (motor standstill).
Chapter 3 – Programming Setting range: 0 to 254 second P2392, Restart frequency Hibernation restart frequency (frequency that the motor output will turn on). Setting range: -200 to 200% NOTE: The +/- signs vary according to the application (heating or cooling sequence). Complete parameter setting by changing over to automatic control.

SED2 Operation & Maintenance Manual Addendum Chapter 4 - BiCo (Binector and Connector) Data Set Functions Introduction The SED2 provides user access levels, set by parameter P0003. User access level 1 gives access to the most frequently used parameters. User access level 2 gives access to more advanced parameters. For example, P0701 sets the function of Digital Input 1 with possible values such as: 1=ON right 12=Reverse 15=Fixed frequency, etc .
Chapter 4 – BiCo Data Set Functions 4. Run the SED2 using input 1 and operate the value using input 2. NOTE: BiCo is a ’reverse’ connection. That is, the output function connects back to the input; it is not possible to tell from P0702 (99) what the digital input is controlling. However, there are many diagnostic parameters that can assist in setting up BiCo functions (see Examples 2, 3, and 4). Example 2: Set P0771 to 37.
SED2 Operation & Maintenance Manual Addendum Using Control and Status Words with BiCo Many SED2 read-only parameters consist of control words. A parameter control word consists of a 16-bit number and each bit represents a particular value. For example parameter r0052 (status word 1) gives value settings such as "Inverter Ready" (bit 0) or "Motor Current Limit" (bit b). Parameter r0052 displays the status of each bit using the vertical segments of the BOP display.
