Operating Instructions SWTD-1000 DYNALCO 4. Principle of Operation 4.1 General The SWTD-1000 is controlled by a microprocessor. It works according to the period measurement principle whereby the input period is measured with subsequent computing of the reciprocal value corresponding to the frequency or speed. The relationship between frequency and speed is established with the Machine factor. The current output and relay control are determined from the speed.
Operating Instructions SWTD-1000 DYNALCO 4.2 Machine Factor The machine factor establishes the relationship between sensor frequency (Hz) and corresponding speed (RPM).
Operating Instructions SWTD-1000 DYNALCO 5. Installation The SWTD-1000 may only be installed by trained and competent personnel. An undamaged SWTD-1000, valid configuration and suitable installation are required. Please note the Safety Instructions in Section 1. The power to the SWTD-1000 should be capable of being disconnected via a switch or other emergency means. Before switching the equipment on the power supply voltage should be verified to be in the permissible range.

Operating Instructions SWTD-1000 DYNALCO 8. Configuration with PC Software 8.1 Software Concept All settings are written via PC to the SWTD-1000 using the RS232 interface and the aid of the user friendly menu driven SWTD-1000 software. The parameter file may be stored, opened, printed and exchanged between the SWTD-1000 and a PC. 8.2 PC Communications Communications with the SWTD-1000 are initiated by the PC via the RS232 interface.

Warning: New configurations only become active after being downloaded into the SWTD-1000 via: SWTD-1000 Æ Write Parameters 8.5.1 System Parameters (Configuration Æ System) Machine Factor The machine factor establishes the relationship between sensor frequency and associated speed. Machine Factor = Frequency RPM See section 4.2 Machine Factor.

Operating Instructions SWTD-1000 DYNALCO 8.5.5 Relay Parameter and Selection of Parameter Set (Configuration Æ Relay control) Parameter set A / B selection As standard parameter set B may be activated via the binary input . If parameter set B is to be deactivated, this setting should be none (always control A) Delay time when switching A <- B This value determines the delay from switching the binary input to the switching from parameter set B to parameter set A.
Operating Instructions SWTD-1000 DYNALCO 9. Operating Behavior 9.1 9.1.1 Power On Analog Output Following power on the output assumes the output range start value. Upon completion of the first measurement the output goes to the corresponding measured value. 9.1.2 Relay Output The parameter set determined by the configuration and binary input is valid from the start.
Operating Instructions SWTD-1000 DYNALCO 9.2.2 Signal Failure In the event of a sudden loss of a good signal no positive edge arrives to complete the measurement or start a new one. Once the minimum measurement time (Fixtime) has lapsed the unit waits for twice the last measurement period following which half the last measured speed is assumed. If the signal remains missing then the measurement approaches zero following an e-function. 9.3 Functions 9.3.
