Both the Z* series Monitors and Control Monitors provide end of travel indication by the means of either an electrical or pneumatic switches or inductive sensors mounted within the enclosure. These are activated by cams / triggers mounted on the rotary shaft. The Monitor enclosure construction comprises of a shaft passing through the enclosure housing and cover (when fitted with visual indicator). The two part enclosure has an integral gasket seal and the shaft has up to two ‘O’ring seals in the bearing areas. The Z* Control Monitor has, located within the enclosure, up to two solenoid coils to operate / control process actuators or cylinders, either double acting or spring return, depending on the model ordered. The Monitor has the option of up to three entries for connection to an external power source in the smaller enclosure and up to five in the larger enclosure. The Control Monitor has two or three respectively depending on whether the one or two coils are selected. The sizes available are; M20 x 1.5p, M25 x 1.5p, 1/2”–14NPT, 3/4”‐14 NPT, Pg13.5 or any other suitable thread that can maintain IP6X ingress rating. ...

Set the top EasiFix cam by pushing down and turning the EasiFix cam until the upper switch is activated. 5.4 Stroke the actuator from one end of stroke to the other several times to check the switch operation. If the switches require adjustment, repeat steps 5.2 to 5.3. BOTTOM CAM TOP CAM LIFT UP, TURN PUSH DOWN, TURN & RELEASE & RELEASE Fig 3 6.0 Field Wiring & Installation. WARNING: The Z* series should always be handled with care when the cover is removed. NOTE: Before electrical installation, please read and follow the wiring diagram located inside the cover. The electrical ratings can be found on the product I.D label. 6.1 Field wiring must be carried out in accordance with site, local and national electrical codes / requirements. This includes special attention to earth bond to the Aluminium or Stainless Steel enclosure using the internal and external earth points provided. 6.2 Installation of this product shall be carried out by competent personnel in accordance with the applicable code of practice such as 60079‐14. ...

- Page 9 7.1.2 Optional Features. No‐Voltage Release (Latching) With the coil first energized, the palm button is then manually moved and latched. The inward movement of the palm button causes the valve to shift. When the coil is de‐energized, the palm button and latching mechanism are automatically tripped, allowing the valve to return to its original position. See Fig. 1 Manual Locking Override Manually depress palm button and rotate clockwise for maintained condition, must manually disengage to return to original position. See Fig. 2 Momentary Override Spring return momentary push type, must hold in to actuate. See Fig. 3 Fig. 1 Fig. 2 Hex Drive Maintained Override Insert allen key in hex head screw and rotate clockwise (4‐5 turns) to shift spool. Valve will stay put until hex head screw is rotated counter clockwise (4‐5 turns) back to original position. See Fig. 4 D/C ‐ Dual Coil Option Five way valves are available with a coil/pilot valve on each end Fig. 3 Fig. 4 of the AVID valve, coil “A” and coil “B”. When coil “A” is energized the valve will shift. If coil “A” is then de‐energized, the valve will remain in this position. The valve will not return to the original state until coil “A” is de‐energized and coil “B” is e nergized. The process is the same for coil “B”. NOTE ‐ For Dual Coil Valves ...

Air Mains and lines should be large enough to avoid excessive pressure loss under conditions of maximum flow. Air lines should be installed with as few restrictions as possible if the cost of compressed air is to be kept to a minimum. Sharp turns in piping should be avoided for more efficient air flow and economical air power. It is advisable to pitch the mains in the direction of air flow so that both gravity and air flow will carry the water to traps or water legs located at frequent intervals. To help in preventing condensed moisture from reaching the point of usage, down pipes should never be ...
- Page 11 7.6 Air Service Equipment. The importance of proper filtration (20 Micron) and lubrication of the air supply to pneumatic equipment can never be over‐emphasized as a means of decreasing friction and preventing corrosion and wear due to moisture and abrasive solids being present in the air supply. At higher pressures than recommended, pneumatic equipment can wear excessively with no significant increase in output and compressed air is consequently wasted. There is much to be gained, therefore, from providing pneumatic equipment with serviced air by including suitable airline filters, pressure regulators and lubricants in the installation. 7.7 Tubes and Fittings. The use of copper, stainless steel, nylon or polyethylene tube is recommended for piping up air circuits and equipment. As a general rule, pipe threaded fittings should not be assembled to a specific torque because the torque required for a reliable joint varies with thread quality, port and fitting materials, sealant used, and other factors. The suggested method of assembling pipe threaded connections is to assemble them finger tight and then wrench tighten further to a specified number of turns from finger tight. The assembly procedure given below is for reference only, the fitting should not be over tightened for this will lead to distortion and most likely, complete valve failure. 1. Inspect port and connectors to ensure that the threads on both are free of dirt, burrs and excessive nicks. 2. Apply sealant/lubricant or Teflon tape to the male pipe threads. With any sealant tape, the first one or two threads should be left uncovered to avoid system contamination. 3. Screw the connector into the port to the finger tight position. 4. Wrench tighten the connector approximately 1 ‐ 2 turns (to seal) from finger tight, again this is only reference – the fitting should NOT be over tightened EXPLODED ASSEMBLY OF 3 & 5 WAY 1.1 Cv AVID VALVE CRANE CO. 280 N.

- Page 12 Product Repair & Service. 8.1 I t is recommended that a periodic visual and operation evaluation is carried out of the Monitor/Control Monitor at least once a year or every 1 million cycles. If the shaft requires lubrication then a suitable (NLGI 2) rated grease such as Rocol Sapphire Lo Temp 2 should be used. Please note that if any other lubricant other than Rocol Sapphire Lo Temp 2 then is shall be compatible with the shaft ‘O’ring material. 8.2 For Control Monitors ONLY ‐ It is recommended that a periodic visual and operation evaluation is carried of the Control Monitor AVID solenoid valve at least once a year or every 1 million cycles. If the spool & seals require lubrication then use Molykote 55 grease. 8.3 Inspection of this product shall be carried out by periodically by suitably trained personnel in accordance with the applicable code of practice such as 60079‐17 to ensure that it is maintained in a satisfactory condition. 8.4 The equipment is not intended to be repaired by the user.
