About product

According to the type of device chosen, the electronic circuit has a 24 VAC/VDC, 110 – 120 VAC or 220 – 230 VAC supply. An output relay with reversing contact ensures high current switching. A twoposition switch allows selection of one of the two time delay ranges: 0.8 to 8 s or 6 to 60 s. The 0.1 to 1.0 adjustable knob allows an initial setting without steps within the previously selected range which can then be adjusted using a stopwatch. Note: We recommend that you allow for temperature drift for the final adjustment of the time delay setting. Drift: – 0.2% per °C. For example, a setting made at 20 °C will yield a time delay shorter by 7% at 55 °C in an enclosure. ( – 0.2% per °C i.e. – 0.2 x 35 = – 7%). The TE5S, which is not affected by these settings, establishes a fixed “lapse” of 50 ms between the opening of contact 15 – 16 and the closing of contact 15 – 18. It is this time delay that prevents from arc short-circuit during wye to delta switching.

The Teach Pendant communicates with the robot computer via a cable (XS20). This cable is also used for the +24V supply and the dual operation chain. The unit's communication signals are fuse-protected on the backplane (F1 and F2). These are PTC type fuses that automatically reset when the short has been corrected. An error in the teach pendant may mean that the rest of the system cannot be used. If the teach pendant seems to be completely dead, but the rest of the system is working correctly, the Teach Pendant may have failed, or a cable break may have occurred. Communication errors between the teach pendant and the I/O computer are indicated by error messages on the teach pendant and also when the red LED on the robot computer lights up.
