The EMO Measure feature allows you to remotely shut down the rack when the mass interconnect is connected to a test adapter. Refer to the following caution for important details.

Caution EMO_MEASURE removes power from the main instruments and interface. The AUX C13 and RCU outlets on the PEP remain powered, but the ETX-1630x does not use those outlets to power any internal equipment. Activating EMO_MEASURE does not put the rack into a service safe state. To completely interrupt power to the rack, disconnect the AC power cable.
Attention EMO_MEASURE coupe l'alimentation des instruments principaux et de l'interface. Les prises AUX C13 et RCU du PEP restent sous tension, mais l'ETX-1630x ne les utilise pas pour alimenter un équipement interne. L'activation d'EMO_MEASURE ne met pas le rack dans un état sécurisé pour l'entretien. Pour interrompre complètement l'alimentation du rack, déconnecter le câble d'alimentation CA.

The EMO Measure behavior depends on the state of the Adapter Detect interlock (J1, pins A33 and A34). Refer to Interlocks for more information about the Adapter Detect interlock.

Use 12 VDC to 24 VDC with EMO Measure pins. The test system monitors the state of the EMO Measure pins only when the Adapter Detect interlock closes. While the Adapter Detect interlock remains closed, the following statements are true:

  • The system does not power on unless DC voltage is present between pins J1, B33 and J1, B34 (EMO Measure + and EMO Measure -). However, providing DC voltage does not turn on the system. You must still push the power button to power on the system.
  • The test system shuts down if the EMO Measure pins lose voltage. Shut down occurs unless the Adapter Detect interlock opens simultaneously.
  • Putting DC voltage on the EMO Measure pins has no direct effect.
Note You must use an external voltage source to provide voltage to the EMO Measure pins while the Adapter Detect interlock is closed for the power button to power on the tester. The test system does not have an always-on source voltage that you can use for this purpose. You can power on the test system without voltage on the EMO Measure pins if the Adapter Detect interlock is open.
