Important: If b1-01 = “3: Option PCB” but a network card is not installed in 2CN, an OPE05 Operator Programming Error will be
displayed on the digital operator and the iQpump drive will not run.

b1-02 Run Source

Start / Stop from Keypad (Parameter b1-02 = 0)
The iQpump drive comes factory programmed for Start and Stop from the Keypad.
The iQpump drive can be programmed to receiver a Run command from four different inputs: digital operator, terminals, serial
communications, or an option PCB.
If the Run command input is determined by the digital operator: Set b1-02 = “0: Operator,” and the hand key will be used to provide
the Run command to the iQpump drive.
If the Run command input is determined by the external terminals: Set b1-02 = “1: Terminals” and initiate an external Run
command by a contact closure between terminals S1 and SN. Refer to Figure 5.6 for the connection diagram of the external Run
command.
Note: To use the external terminals requires the iQpump drive to be set to “Auto” mode by pressing the Auto key.

If the Run command is determined by Serial Communications: b1-02 = “2: Serial Communications,” and initiate the Run command
through the serial communications. Refer to
Figure 5.5 (in the previous b1 sequence section) for the connection diagram for serial
communications through the RS232 / 485 terminals. The following is a simple setup procedure for programming the iQpump drive and
PC Serial communications to initiate Run and Stop commands through serial communications. Appendix: E has further details on the
Modbus communications.
1. Program b1-02 = “2: Serial communications.”
2. Program the following H5 parameters:
H5-01 Serial Communication Address: 31
H5-02 Serial Baud Rate: 9600 Baud (setting 3).
H5-03 Serial Communication Parity Selection: None (setting 0).
