1 Introduction Scope The purpose of these instructions is to describe the adaptor unit Tina 7A and to provide the necessary information required for installation and operation. Audience This document is intended for authorized installation personnel. Prerequisites It is assumed that the reader of this document has knowledge of the following: • Basic knowledge of ABB Jokab Safety products. • Knowledge of machine safety.
2 Overview General description ABB Jokab Safety adaptor units are used to adapt conventional safety sensors where the safety relies on e.g. oneor two-channel static signals, OSSD outputs, or short circuit detection, to the dynamic safety circuit monitored by a Vital safety module or Pluto safety-PLC. Tina 7A is used to adapt safety sensors with mechanical contacts to the dynamic safety circuit.
3 Connections 9-pin connection block: 1 ) +24 VDC 2 ) Dynamic signal input 3 ) 0 VDC 4 ) Dynamic signal output 5 ) Information 6 ) Loop-A1 7 ) Loop-A2 8 ) Loop-B1 9 ) Loop-B2 NB: Shielded cable is recommended between this unit and the rest of the safety circuits. Caution! The safety loop cables (connected to terminals 6-9) should not be longer than 150 mm. The cables should be as short as possible as longer cables increase the risk for electrical interference.
Connection examples Caution! All cable colours according to ABB Jokab Safety standard cables. 2TLC172139M0201, rev. B 2014-11-26 7 www.abb.
4 Installation and maintenance Installation precautions First attach the unit on a 35 mm DIN rail. Then attach the safety-loop to the connection block (nr 6-9). Finally, attach the cables to the connection block (nr 1-5). Warning! All the safety functions must be tested before starting up the system. Maintenance Warning! The safety functions and the mechanics shall be tested regularly, at least once every year to confirm that all the safety functions are working properly (EN 62061:2005).
