OVERVIEW The Essex Inc. MOCS, or Machine to Operator Communication System, is designed to work in conjunction with the Essex process control products to automatically audibly alert the operator via wireless communication to any off-standard condition that requires a machine shut down or alarm. MOCS allows one operator to monitor multiple machines without the necessity of constant visual contact. The language of the alerts is selectable.
INSTALLATION Requirements: FCC allocated radio frequencies for wireless communication Mounting the Control Panel Mount for convenience , isolated from machine vibration Connections to the Control Panel 120 VAC power required Connect MOCS Interface panel as per included wiring diagram (if applicable) Run relay contact to Process Control panel or MOCS Interface panel must be a maintained contact for MOCS to function properly 6
OPERATION Whenever a stop event occurs MOCS will automatically alert the operator with an audible alarm, which will repeat on a customizable timed interval until the event is remedied. The audible alarm will automatically cease upon the machine re-starting. Select the alarm language. The Language switch is located on the face of the MOCS panel. For the Basic MOCS, turn On belt-pack receiver and place ear buds in ears. For MOCS plus and Supervisor MOCS, turn On the transceivers/ radios with the power knob.
OPERATION continued Charging the Radio for MOCS Plus Charge lasts for approximately 8 hours. Charger is included with system and is located on the control panel. Slide radio into the charging slot of the charger, making sure that the metal contacts on the radio mate securely with the charger terminals. The charger indicator light will shine red while charging. Charge time is approximately 2 hours. When charging is complete the charger indicator light will shine green.
