2 Introduction The is an interface module between the Safety Sensor and the machine controls. A Safety Sensor can be a Safety Mat, Safety Edge, Safety Bumper, 2 or 4 wire Safety Sensor. The allows the Safety Sensor to run on small voltage and current values while also allowing the output to control high voltages and currents of the machine controls. Together, these components form a Safety System allowing safe interface between Safety Sensor and Machine. As a system, the two parts work in conjunction with one another to continuously monitor the machine safety system and control power to the dangerous conditions of the machine. When a person or object, i.e. forklift, comes in contact with the Safety Sensor, the internal Patented Zippswitch Sensing Strip closes and a change of state is detected by the controller. This action causes the output contacts to open and shut power off to the machine. Once the obstruction is removed and any danger is cleared, the system will need to be reset, manually or automatically, restoring power to the machine. DIN Rail Enclosure Reset Every includes a user selectable Manual and Automatic reset circuit. This feature allows the user to choose between different reset modes. It is up to the user to determine the level of safety required to provide the highest level of safety which prevents injury or damage to personnel and machinery. Manual Reset Manual Reset mode provides the highest level of reset control in the safety circuit. When the Safety Sensor and Machine s are connected through the, the machine operator must initiate a reset function before allowing power to energize the machine. In Manual Reset mode, a normally open, momentary push button switch is connected between terminals 3 & 4 of the. When power is applied to the, the machine will not energize. The machine will energize after the dangerous area is clear, the Safety Sensor is clear and the momentary push button is pressed and released. After this procedure, the output contacts of the will change state from Normally Open (N/O) to the closed position, allowing power to energize the machine. The machine will remain energized and operate in normal mode until the Safety Sensor is contacted and tripped, or a fault in the Safety System is detected. The machine can only be re-energized by following the steps above.

3 Automatic Reset Automatic Reset mode provides the lowest level of reset control in the safety circuit. When the Safety Sensor and Machine s are connected through the, the machine will energize when power is applied to the. In Automatic Reset mode, a jumper wire is connected between terminals 3 & 4 of the. When power is applied to the, the machine will energize. The machine will automatically energize if the Safety Sensor is clear. The output contacts of the will change state from Normally Open (N/O) to the closed position, allowing power to energize the machine. The machine will remain energized and operate in normal mode until the Safety Sensor is contacted and tripped, or a fault in the Safety System is detected. The machine will automatically reset when the Safety Sensor is cleared. Wall Mount Enclosure Fault Detection s are designed to remove power to the machine if a fault is detected. A fault can be a loss of power, broken/shorted Safety Sensor wire, shorted Safety Sensor, faulty Safety Sensor, Welded Output Contact, internal electronic circuit fault. Types of Safety Sensors s are designed to be used with Safety Mats, Safety Edges, Safety Bumpers and Safety Sensors with 4-wire or 2-wire safety circuits. 4-wire Safety Sensors A 4-wire Safety Sensor is designed to have an accessible output wire at each endpoint of the Safety Sensor Circuit. This allows the outputs of the Safety Sensor to be constantly monitored. When connected to a 4-wire Safety Relay, the Safety Sensor is recognized as an inline series circuit. This allows the to continually monitor the conditions of the Safety Sensor in all modes of operation.

4 2-wire Safety Sensors A 2-wire Safety Sensor is designed with an internal circuit within the Safety Sensor. The circuit is connected to the opposite end of the Safety Sensor from the output 2-wire cable. When connected to a 2-wire Safety Relay, the Safety Sensor is recognized as an inline series circuit. This allows the to continually monitor the conditions of the Safety Sensor in all modes of operation. The advantage of using a 2-wire Safety Sensor is the reduction of cables and complexity of the overall Safety System. Safety Outputs Intrinsically Safe Enclosure s include a minimum of 2 safety outputs. Each output is cross monitored for redundancy. The internal Safety Relays are manufactured to include Force-Guided Contacts. The contacts are designed to break away if they become welded. If this occurs, the Safety Outputs of the will result in a loss of power to the machine. s allow for use in machines requiring high voltage and current to operate properly. The output rating for s is 6 amps and 400 volts. Auxiliary Output s may include an optional Auxiliary Output. These outputs are designed to run low amperage devices such as beacons, horns and warning lights. Auxiliary Outputs are not designed to be used as a Safety function of the Safety System. Multiple Safety Sensors s with multiple Safety Sensor inputs allow for 2 or more Safety Sensors to be connected to one. This allows for independent control of the machine from different Safety Sensors at different points on the machine. Indicator Lights s include visual indicators that display different functions and statuses of the Safety System. These include Power, Safety Output, Auxiliary Output, and Sensor Off status. Input Power Each model has different input voltage requirements. These include VAC and 24 VDC.

5 Model DIN-24MAZ The DIN-24MAZ is a designed to interface Safety Mats, Safety Edges, and s to a Machine. When the Safety Sensor is tripped, the will remove power to the machine.
