RAD1-42-2E Oven Owner’s Manual Version 1 1.5.4. ABOUT THIS MANUAL 9 Power Line voltages may vary in some geographies. If the line voltage for your RAD1-42-2E oven varies more than 10% from the oven voltage rating, electrical components such as relays and temperature controls may operate erratically. If the line voltage is lower than the oven voltage rating, heat-up time may be significantly longer and motors may overload or run hot.
RAD1-42-2E Oven Owner’s Manual Version 1 SAFETY 10 2. Safety 2.1. Safety Information Do not work on the RAD1-42-2E oven without reading and understanding this section which contains important information and warnings. Ignoring these warnings can result in death, serious injury or damage to the machine and product. 2.1.1. Lockout Machine lockout places the RAD1-42-2E oven into a zero energy state and prevents accidental machine start up.
RAD1-42-2E Oven Owner’s Manual Version 1 2.2. Maintenance Only qualified and trained personnel should perform maintenance or repair. 2.3. Electrical Power Only qualified and trained personnel should perform electrical maintenance or electrical repair. Danger! Contact with energized electrical sources may result in serious injury or death. Before performing maintenance, disconnect all electrical power from the machine. Use a padlock and lockout all disconnects feeding power to the machine.
RAD1-42-2E Oven Owner’s Manual Version 1 SAFETY 12 2.5.1. Optional Disconnect Switch The RAD1-42-2E oven has an optional Disconnect Switch (Figure 1). This Disconnect Switch is located on the front of the oven and connected to the load break switch behind the panel that disconnects or connects power from the main line. When a risk of personal injury or damage to the RAD1-42-2E oven exists, turn off the Disconnect Switch. This shuts off all electrical power to the oven. Figure 1. Disconnect Switch.
RFD1-42-2E Oven Owner’s Manual Version 1 3. THEORY OF OPERATION 13 Theory of Operation 3.1. The RAD1-42-2E Oven Despatch RAD1-42-2E ovens (Figure 2) effectively distribute heat and have very fast processing times compared to other lab ovens their size. Because of effective heat distribution and fast processing times, the RAD1-42-2E ovens are especially useful for testing, preheating, sterilizing, drying, aging and curing, along with other production applications.
RFD1-42-2E Oven Owner’s Manual Version 1 THEORY OF OPERATION 14 conditions, load distribution, heat-up rates, cool-down rates, desired temperature uniformity and, most importantly, the desired operating temperature. Carefully consider existing engineering tradeoffs while using guidelines to determine the fresh air damper setting. In general, the damper should be set so that the amount of fresh air flowing into the chamber agrees with the desired operating temperature conditions.
RFD1-42-2E Oven Owner’s Manual Version 1 THEORY OF OPERATION 15 uniformity improves. The slightly pressurized chamber produces the effect of "pushing" air to the corners of the chamber. Typically the corners of the chamber improve with respect to temperature distribution while the core of the chamber maintains excellent uniformity characteristics regardless of damper position. Pressurization of the chamber typically is a factor when the chamber is loaded heavily.
RFD1-42-2E Oven Owner’s Manual Version 1 THEORY OF OPERATION 16 Figure 4. Protocol 3 Operator Interface. 3.3.1. Optional High Limit Audible Alarm High Limit audible and visual alarm is a red light and small alarm horn located on the front of the control panel. The alarm is sounded if a High Limit condition occurs. A switch is provided to silence the alarm. This alarm has a range of 80dB at 2 ft (0.6 m). 3.3.2.
RAD1-42-2E Oven Owner’s Manual Version 1 4. ASSEMBLY & SETUP 17 Assembly & Setup Assembly and Setup provides directions for unpacking and installing your RAD1-42-2E oven. 4.1.
