The Automation Technician is the operational backbone of a cannabis production facility, ensuring the seamless function of the technology that governs everything from cultivation environments to cannabinoid extraction. This role bridges the gap between the physical machinery and the digital control systems that dictate its behavior. In an industry where product consistency, regulatory compliance, and operational efficiency are paramount, the automation systems are the central nervous system. The technician is the specialist who keeps this system healthy and responsive. They work directly with Programmable Logic Controllers (PLCs), Human-Machine Interfaces (HMIs), and Supervisory Control and Data Acquisition (SCADA) systems. These systems manage the precise environmental conditions for plant growth, the critical safety parameters for solvent-based extraction, and the high-throughput mechanics of packaging lines. The position requires a unique blend of skills, including electrical troubleshooting, mechanical aptitude, and software literacy. The technician's work directly prevents catastrophic equipment failure, ensures worker safety in hazardous environments, and guarantees that the final product meets exacting quality and compliance standards. Their performance is measured by equipment uptime, process stability, and the accuracy of the data logged for state regulators.
The day begins with a system-wide status review on the central SCADA dashboard. The technician analyzes trend data from the overnight operations of the cultivation facility's Building Automation System (BAS). The focus is on verifying that humidity, temperature, and CO2 levels in each flowering room remained within their programmed setpoints. An anomaly is detected in Flower Room 7, where the CO2 parts per million (PPM) dropped below the target for a 30-minute period. The technician cross-references the BAS logs with the maintenance schedule and hypothesizes a sticky solenoid valve on the CO2 injection line. A work order is created in the Computerized Maintenance Management System (CMMS) to inspect and service the valve during the room's next dark cycle to avoid disrupting the plants' photoperiod.
Next, the technician moves to the extraction lab for a scheduled preventative maintenance task. Today's focus is the calibration of pressure and temperature sensors on a large-scale CO2 extraction vessel. Using a certified pressure gauge and thermocouple, the technician connects to the vessel's instrumentation. They verify that the readings displayed on the local HMI match the values from the calibrated test equipment. Any deviation is corrected by adjusting the sensor's electronic transmitter. Every step, including the serial numbers of the test equipment used, is meticulously recorded in a calibration logbook. This documentation is not just good practice; it is a critical compliance record that will be scrutinized during a state regulatory audit to prove the process is controlled and repeatable.
Midday brings an urgent call from the packaging department. The automated bottling line for tinctures has stopped, flagging a 'vision system error' on its HMI. The technician arrives and observes the line. The robotic arm is failing to correctly place caps on the bottles. After placing the system in a safe maintenance mode, the technician connects a laptop to the vision system's controller. The diagnostic software shows that the camera is struggling to identify the bottle's position on the conveyor. The technician identifies the root cause: a slight misalignment in the conveyor guide rail, causing the bottles to sit a few millimeters off-center. A quick mechanical adjustment is made, the vision system is recalibrated to the new bottle position, and a test run confirms the issue is resolved. The downtime is logged, along with the corrective action, to track equipment reliability trends.
The afternoon is dedicated to project work. The facility is commissioning a new automated trimmer. The Automation Technician works alongside the OEM's representative to complete the final I/O checkout. This involves systematically testing every sensor, motor, and actuator on the machine. They force inputs on the PLC to ensure the corresponding outputs fire correctly. For example, they'll manually trigger the 'guard door open' sensor to verify the PLC immediately cuts power to the trimming blades. This detailed inspection ensures the equipment is safe and operates according to its design specifications before it is handed over to the production team. The day concludes with updating all relevant documentation, including electrical drawings and maintenance procedures for the new asset, and a final check of system alarms before the shift ends.
The Automation Technician's duties are organized across three primary pillars that directly support the facility's financial and operational health:
The Automation Technician directly influences key business performance metrics through their technical expertise and diligent oversight:
