We reserve the right BO 5988 / 02.06.09 e 1 0221562Notes Technical Data Jumper assignment for functions: Output Activation via On pushbutton / or automatic On function Contact On push- Jumper Function BO 5988.48: 3 NO, 1 NC indicator contact button BO 5988.61: 6 NO, 1 NC indicator contact Y1 - Y2 X5 - X6 BO 5988.62: 6 NO, 1 NO indictor contact BO 5988.47: 3 NO, 1 NC indicator contact The output contacts are switches only 1 NO release delayed after operation of the On pushbutton. The NO contacts 13...63 / 14...64 are Line fault monitoring at the On pushbutton safety contacts. The NO contact 77/78 can be use as safety contact for units Automatic On function for operating with time delay up to max. 30 s. voltage Off/On or after emergency ATTENTION The NC contacts 81-82 M8687 stop release or one NO contact 83-84 can only be used for monitoring. Line fault detection at the On pushbutton: Operate time The output contacts cannot be closed if the On pushbutton is already manual restart: typ. 30 ms closed before the voltage is applied to S12, S22 (also in the event of a line automatic restart: 1 s fault at the On pushbutton). Release time A line fault at the On pushbutton which occures after activation of the opening in secondary circuit device is recognized when swichting-on takes place again and closing of (S12-S22): 30 ms 50 % the output contacts is then prevented. opening in supply circuit If a line fault occurs at the On pushbutton after the voltage is already BO5988.47, BO 5988.48: 100 ms + 50 % present at S12, S22, undesired activation will take place, because this BO 5988.61, BO 5988.62: 50 ms + 50 % line fault does not differ from the normal closing function. Time delay t : Auxiliary supply is not necessary v The gold-plated contacts of the BO 5988 also mean that this module is during elapse of time: suitable for switching small loads of 1 mVA ... 7 VA, 1 mW ... 7 W in the BO 5988.47/1 : 0,1 ... 1 s 0,3 ... 3 s range 0,1 ... 60 V, 1 ... 300 mA. The contacts also permit the maximum 0,5 ... 5 s 1 ... 10 s switching current. However, since the gold plating is burnt off at this BO 5988.47/2 : 1 s, 3 s, 5 s, 10 s current level, the device is no longer suitable for switching small loads Auxiliary supply must be connected after this. during elapse of time: The PE terminal permits operation of the device in IT systems with BO 5988.47/4 : 0,1 ... 1 s 0,1 ... 1 min insulation monitoring and also serves as a reference point for testing the 0,3... 3 s 0,3 ... 3 min control voltage. The internal short-circuit protection will be bridged on DC 1 ... 10 s 0,5 ... 5 min devices, if the protective ground is connected to terminal PE. 3 ... 30 s 1 ... 10 min One or more extension modules BN 3081 or external contactors with BO 5988.47/5 : 1 s, 3 s, 10, 30 s positively-driven contacts may be used to multiply the number of contacts 1 min, 3 min, 5 min, 10 min of the emergency stop module BO 5988.
