Chapter 4: System Installation Remote Manual Mode The optional Front Panel provides for a Manual Mode circuit. See Remote High Power On/Off Control on page 62 for further details about the customer Remote Manual Mode circuitry. The Front Panel, or a user-supplied panel, must be incorporated into the robot workcell to provide a “Single Point of Control” (the pendant) when the controller is placed in Manual mode. Certain workcell devices, such as PLCs or conveyors, may need to be turned off when the operating mode switch is set to Manual mode. This is to ensure that the robot controller does not receive commands from devices other than from the pendant, the single point of con- trol.
If the user needs to control the Manual/Automatic mode selection from other control equip- ment, then a custom splitter cable or complete replacement of the Front Panel may be required. See Front Panel Schematic on page 60. In this situation, a pair of contacts should be wired in series with the Front Panel Manual/Automatic mode contacts. Thus, both the Front Panel, or the user-supplied panel, and the customer contacts need to be closed to allow Automatic mode. WARNING: Do not wire user-supplied Manual/Automatic contacts in parallel with the standard Front Panel, or the user-supplied panel, switch contact.
This would violate the “Single Point of Control” prin- ciple and might allow Automatic (high-speed) mode to be selected while an operator is in the cell. User Manual/Auto Indication Two pairs of pins on the XUSR connector (pins 9, 22 and 10, 23) provide a voltage-free contact to indicate whether the Front Panel and/or remote Manual/Automatic switches are closed. The user may use these contacts to control other mechanisms (for example, conveyor, linear modules, etc.) when Manual mode is selected. The load on the contacts should not exceed 40 VDC or 30 VAC at a maximum of 1 A. WARNING: Any safeguards that were suspended must be returned to full functionality prior to selecting Automatic Mode.
User High Power On Indication In the optional SmartController EX, eV+ controls a normally-open relay contact on the XDIO connector (pins 45, 46, see the table System Installation on page 35), that will close when high power has been enabled. The user can use this feature to power an indicator lamp or other device, that signals High Power is On. The limit on these contacts is 1 A at 30 VDC or 30 VAC. Remote High Power On/Off Control The easiest and most effective way to provide the high power on/off control in a remote loc- ation is to mount an optional Front Panel in the desired location with an extension cable.
However, if the user needs to control high power on/off from other control equipment or from a location other than the front panel, then a custom splitter cable will be required. See the Front Panel schematic (Front Panel Schematic on page 60) for details of the Front Panel’s wiring. In this situation, a second momentary contact for high power on/off would be placed in parallel Hornet 565 Robot User's Guide, 14608-000 Rev C Page 62 of 156
