mounted. Clamp the cable shield to the earthed DIN-rail. Remaining wires are connected to corresponding Vital/Pluto terminal block pins. •Tina 1A must be connected to unused M12 connectors. 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). In case of breakdown or damage to the product, contact the nearest ABB Jokab Safety Service Office or reseller. Do not try to repair the product yourself since it may accidentally cause permanent damage to the product, impairing the safety of the device which in turn could lead to serious injury to personnel. Testing of the safety functions Make sure the safety unit is working properly by following these steps: •Interrupt the dynamic safety circuit before this unit. The LEDs on all Tina units attached should flash between green and red. •Interrupt protection at the last connection (i.e. connection nr 8). The voltage over pin-4 in the 13-pin connection block should be 0 VDC. Troubleshooting Problem Expected causes of faults Checking and measures to take No dynamic signal out (0 VDC) One or more of the sensors open Check status of the sensor/unit(s) Interference between two safety light beams Check status of the light beams 24 VDC input to pin-2 (no dynamic signal) Check if there is 24 VDC to input (pin-2). If Yes, check cable or unit before and fix it. Loss of power supply Check 24 VDC / 0 VDC power supply Warning! Replace defected unit with a new one and never bypass the safety circuit using Tina 1A or any other solution.2TLC172142M0201, rev. D 8 www.abb.com/jokabsafety 2014-03-11

5 Operation Information output signal attributes Summary information output signal: The summary information output of the unit (pin-13 on the connection block) is set either high (+24 VDC) or low (0 VDC) depending on four different input signals (pin-2 on the connection block): •Dynamic signal- Dynamic signal input exist, i.e. the safety circuit is OK up until this unit •No dynamic signal- Dynamic signal input does not exist, i.e. the safety circuit is interrupted before this unit. •+24 VDC- A constant +24 VDC signal is applied = high (H) •0 VDC- The pin is connected to 0 VDC = low (L) The summary information output signal depends on the input signal according to the table below. Note that if the safety is interrupted on either of the devices connected to any of the female connectors (connectors 1-8), the summary information output signal is always low (L). Input signal (pin-2) Dynamic signal No dynamic signal +24 VDC 0 VDC Info output signal (pin-13) High Low Low Low The delay for switching the information signal output from high to low (H L) and low to high (L H) is given in the table below.
