3 Indicating Meter for Instrumentation DEF-S (Single-pointer type) DEF-7S (Single-pointer type) DEF-W (Two facing pointers type) DEF-7W (Two facing pointers type) [Overview] This meter has the optimal structure and characteristics to function as an indicator for various process control systems such as power, petroleum, chemical, metal and paper plants. A state-of-the-art instrument panel receiver with an elegant, stately design and extensive functionality; this highly reliable product makes control station quality even higher. Features Comparative measurements for measurement control of series such as directed standard values and measurement values can be conducted with ease because the DEF - W and DEF - 7W are integrated in a pair meter structure. Optimal for system display panels and graphic monitoring panels. Appropriate for areas with dense instrumentation as very little space is required for installation. Two or more units can be neatly connected. Tag plates are attached to the top and bottom to display information such as measuring point name and tag number. The scale is brighter, larger and easier to read, making it easy to perform a series of control operations. Parts such as the zero-point adjuster and the scale plate can be replaced because the meter unit can be easily removed from the front side. 7 DEF-S only DEF-W only Specifications ) Direct-acting - Input signal is applied directly to the coil.

6 [EF- Instruction Manual] (The zero-point adjuster and scale plate of the the DEF-S and DEF-W can be replaced simply by removing the meter unit from the front side.) [Removing the Meter] Stopper. Hook your finger on the bottom part of the name plate and pull it out. First the name plate comes out, then the meter unit comes out until it protrudes by approx. 7mm. At this point the clamping mechanism is released. The name plate will not come out any further, but be careful because the meter unit may pop out if it is facing downward.. The meter unit can be completely removed, but the last part has a stopper on it, so remove the unit by pulling up and towards yourself.. The meter unit and meter frame can be completely separated by pulling out the connector.. Insert the connector followed by the main unit to install the meter unit. After pushing in the meter unit part-way, push in the name plate, then push in the meter unit the rest of the way until you hear it lock into place with a click. The name plate and meter unit can be pushed into place in any order, but make sure afterwards that the meter unit does not come out when pulled on. Connector [Adjusting Zero-point] Maximum Scale Value Adjustment. Hook your finger on the bottom part of the name plate and pull it out. First the name plate comes out, then the meter unit comes out until it protrudes by approx. 7mm. At this point the clamping mechanism is released. The name plate will not come out any further, but be careful because the meter unit may pop out if it is facing downward.. Adjust zero-point after pulling the meter unit out into a position where the adjustment can be carried out. Adjust zero-point on the side face by turning the circular plate printed with [ZERO ADJ]. This is on the same side as the [ ] symbols in the same color as the pointer. Turn the plate using a screwdriver that fits inside the groove properly. Using an inappropriate size may break the groove.. After adjusting zero-point, push in the meter unit part-way, push in the name plate, then push in the meter unit the rest of the way until you hear it lock into place with a click. The name plate and meter unit can be pushed into place in any order, but make sure afterwards that the meter unit does not come out when pulled on. [Replacing the ] [Replacing the Scale Plate]. The upper name plate can be removed by hooking your finger around the upper part and pulling towards you.. The lower name plate can be removed by hooking your finger around the lower part and pulling it out, then pushing an object such as a screwdriver into the tab on the side and pulling out and towards you. It can be easily removed by simply pulling out one of the tabs.. Both the upper and lower nameplates can be attached by pushing them in.. Pull the meter unit out from the meter frame.. Take out the two screws and remove the cover.. Take out the two screws and replace the scale plate cassette.. Do not touch the pointer when attaching the cassette or cover. [For the EF-W] [Attaching the Meter]. Insert the meter from the front side of the panel.. Use the attachment brackets to fix the top and bottom of the meter in place from the back. Scale Plate Snap. Pull the meter unit out from the meter frame.. Take out the two screws and remove the cover.. Replace the left and right scale number plates () after removing the scale plate ()..

11 Instruction Manual () Item Instructions Diagrams and Examples Mounting () () () () () () Make mounting holes according to the panel cutout pictured in the outside dimensions diagram. The materials of the attached panel are as indicated on the label of the meter. An error within.% of the maximum value occurs when the panel materials are incorrect. Insert the escutcheons between the panel face and the meter's mounting area when installing the meter on the panel. Use Escutcheon A for the edge and B between meters when installing multiple units in tandem. Use the escutcheons to prevent the leakage of light from the underside of the panel due to gaps in the meter mounting. To install the meter onto the panel, first position the attachment bracket in the position of the thin line in the figure. Next, put the meter into the panel, loosen screw C, tighten C in the position of the thick line, then use setscrew D to affix the meter tightly to the panel face. A panel up to mm thick can be installed.

If the pointer is deviating, adjust it using the following procedure. () For meters with a value from to maximum, adjust the zero-point adjuster on the front by using a to.mm flat-head screwdriver to rotate the pointer left or right. () For meters without a scale (expanded scale meters), such as the - ma meter, apply electricity equivalent to the minimum scale value and adjust the zero-point adjuster by rotating the pointer left or right with a screwdriver to match the minimum scale value.
