evaluation systems time delay relay 1700 1 functions and time ranges adjustable via DIP-switch large time ranges with high repeat accuracy 2 integrated relays / change-over contacts remote control via remote potentiometer wide range power supply DIN-housing for mounting on DIN-rail LED function display multi-function time delay relay 8 functions and time ranges description The DIP switches on the front of the unit are used to set the times, functions and output relays. Eight functions are available, see function diagrams. The potentiometer on the front plate is used for the fine adjustment of the time settings. The time may be set in eight ranges from 0.1 second to 300 minutes. Green and red LEDs serve to display the operating mode. The green LED signals the operational readiness. The red LED shows the energizing of relay 1. In the star/delta function the red LED will also light up when relay 2 energizes. As soon as the operating voltage has been applied the internal processor loads the function and the fundamental time range that has been set on the DIP-switches. New settings on the DIP switches will not become effective until after the operating voltage has been interrupted and then reapplied. Time-settings that have been altered through the potentiometer are acquired during the operation. mounting and connecting The housing is mounted on a 35mm DIN-rail. The operating voltage should be applied to terminals A1 and A2. The make contacts (terminals 15/16/18 and 25/26/28) of the two integrated relays can be wired as you like. They operate differently depending on the selected function. The floating encoder contact that is required for some functions is connected to the B1 and B2 terminals. If no floating contact is available an external control voltage must be connected to terminal B2 corresponding to the potential on A1. The remote potentiometer is connected to the terminals Z1 and Z2. The maximum resistance of the encapsulated potentiometer is 10kÙ. The feed line must be shielded and earthed and must not be longer than one meter. Any remote potentiometer that is connected is recognized automatically by the device after the operating voltage has been applied. important notes  for direct current operation connect the positive pole to terminal A1  terminal B1 has always the same potential as terminal A1 (possibly supply voltage)  do observe the technical data on the reverse  a remote potentiometer with metal axis must be earthed  the device may only be operated with the plexiglass cover in place  after the device has been successfully installed, no manipulation with tools should be carried out whilst it is operating design 22.5 x 75 x 110mm multi-function time delay turn-on turn-on, instant turn-on timed turn-off cycle, pulse cycle, pause pulse forming star/delta ipf electronic gmbh Kalver Straße 27 D-58515 Lüdenscheid subject to alteration! version: November 2008 Fon +49 (0) 2351 / 9365-0 Fax +49 (0) 2351 / 936519 www.ipf-electronic.de E-Mail: info@ipf-electronic.de
