The white plastic tab indicates the voltage for which the instrument has been configured. This has been factory set for the voltage appropriate to your country (120 or 240 VAC: 50 or 60 Hz). If the voltage is incorrectly set, you should reset it to the proper value before proceeding further. The recorder will not function in 100 and 220 VAC positions. Insert the blade of a small screwdriver into the slot next to the connector and pry open the fuse block. Pull the fuse block straight out. Using tweezers or a pair of longnose pliers. pull the voltage selector card straight out. Orient the plastic indicator for the proper voltage as indicated in Figure 5, then press the selector card back into place. Insure that the proper fuse is inserted for the voltage selected as follows: SA S.B. for 120 VAC and 25A S.B. for 240 VAC Snap the fuse block cover back into place. Power Cord: Power to the detector is provided by a standard modular power cord assembly. Connect the power cord to the receptacle next to the fuse block. CHART PAPER INSTALLATION 1. Remove masking tape from new roll of chart paper and cut or tear each side to form a blunt point at the center. (DO NOT FOLD.) 2. Pull the knob on the right side of the chart paper core support, located on the rear panel of the recorder. Install paper, making sure it seats evenly on the two core supports. Release knob. 3. Lift the pen lift lever (on the left side of the instrument) to the full upright position. 4. Manually feed the pointed paper under the pen cover and across the writing area. S. Pull the paper under the paper hold down and across the paper sprockets, making sure the holes in the paper sit evenly on the sprockets. 6. The paper is now loaded for operation. PAPER RELEASE SYSTEM Your recorder is equipped with a sprocket release that enables you to advance or rewind the paper manually. To advance or rewind the paper manually: Lift the pen lift lever to the full UP position. The paper may now be moved forward or backward as desired To re-engage chart drive: Retum pen lift lever to the full DOWN position. NOTE: After manual advancement or rewind there may be a short delay, depending on chart speed selected, then the chart will run at the selected speed. PEN INSTALLATION 1. Remove the pen cap and store it where it can easily be found. Pens can be left uncapped for long periods of time, but greater pen life results from capping when not in use. 2. Slide the pen into the pen carriage and gently push back until the nib is firmly seated against the carriage. 3. Return the pen lift lever to the original down position. GROUNDING For best performance, the green (or green and yellow) ground wire in the power cord for the recorder and the signal source should share a common water pipe ground, The green (green and yellow) wire in the power cord. is connected to the recorder ground (Chassis), but not to the signal input. If the signal input does not have a third wire in its power cord, or if the instrument is not grounded, connect a wire between the recorder ground (green terminal) and the chassis of the signal source. In case of large normal-mode signals, particularly 120Hz, connect the recorder ground (green terminal) to the source of the normal-mode signal, or to the negative recorder input (black terminal.) INPUT SIGNAL CONNECTIONS This instrument requires a DC voltage input. Signal sources with current outputs will require a shunt resistor across the + (red) and - (black) inputs. Ohms law may be used to compute the proper value for a given input range. The formula is: R=E 1 Where Eis the recorder span range selected in volts. 1 is the maximurn current signal to be recorded in amps. R is the resistance of the shunt resistor in Ohms. Electrical connections are made as follows: Signal source positive to recorder Red (+) terminal. Signal source negative to recorder Black (-) terminal. Right hand chart zero is standard on the recorder. Positive going signals drive pen to the left, If an opposite presentation is desired, reverse the input leads and use the zero adjust control to position the pen to the opposite side of the chart. Negative signals will now drive the pen to the right. NOTE: This unit is calibrated for right hand zero. Reversal of the input leads may yield a +3% full scale error. RECORDING PROCEDURE With chart paper and pends) installed and recorder plugged into proper AC source (corresponding to the conversion slide switch on the back of the recorder) perform the following steps for routine recording. 1. Tum power switch on and chart switch off 2. Set input span to desired range and attenuator to Cal position. 3. Set record/stand-by switch to stand-by position. 4. Zero pen to right side of chart using zero control knob. 5. Set record/stand-by switch to "REC" position. -11- 6. Adjust input span and attenuator for desired full scale range to best display input signal. 7. Tum chart drive on and set chart speed as desired. Make sure the chart paper holes are properly aligned with sprocket teeth. 8. REMOTE CHART CONTROL Place the Remote-Local slide switch in the “Remote” position. To start the chart drive from a remote location, apply a contact closure between pins 5 and 6 of the remote control connector located on rear panel of recorder. The chart will stop when the contact is opened. NOTE 1: When switching from one sensitivity range to another, it may be necessary to rezero the pen. To do so, place REC/STBY switch in “STBY* readjust the zero knob. (The zero control has no stops at the end of mechanical travel) Return REC/STBY switch to “REC”. NOTE 2: In most models, the input resistance is so high that the pen may drift when no connections are present at the input. NOTE 3: If the-pen is physically stalled on the chart for a few seconds, the servo system will shut down to protect the motor. The best way to reset the system is to turn the recorder off for about 5 seconds, and then back on. Pen should reactivate and continue to record normally. If the shutdown resulted from an Overrange, the recorder will operate normally as soon as the input signal decreases to a level which is within the selected span range. -12- GENERAL THEORY The DC input signal to the recorder is first filtered, then amplified by the preamp to a level which is less susceptible to noise and interference. This conditioned signal is then applied to the servo amplifier which continuously compares it to the feedback signal developed by the servo potentiometer. The difference between these two signals is a positive or negative error signal that is amplified and used to drive the servo motor, which is coupled to the servo potentiometer, in a direction as to reduce the error signal to zero. Since the recorder pen is mechanically coupled to the servo motor and servo potentiometer, its position on the chart represents an accurate and continuous permanent graphic record of the input signal (See Figure 6). CHART RECORDER POWER SUPPLY AC line voltage is reduced by stepdown transformers and converted to DC by solid state rectifiers and regulators. A stable DC voltage. generated by a temperature compensated zener diode, is used as a reference for the servo pot. PEN DRIVE SYSTEM A DC servo motor is used to control the servo pot and recorder pen by means of a gear driven servo drum assembly. The pen is attached to a drive cable which is wrapped around and secured to the drum. As the drum rotates, the pen is moved across the chart proportionate to the amount of drum rotation. CHART DRIVE SYSTEM In this simple. reliable system an internal crystal oscillator generates pulses which are divided down by integrated circuit logic. The chart speed switch selects the appropriate pulse rate to drive the stepper motor at the desired speed. (The crystal frequency is not a function of line frequency. therefore chart speeds are completely independent.) -13- FEEDBACK ATTENUATOR* * RANGE (SPAN) SWITCHING GAIN CONTROL © SIGNAL INPUT FILTER SERVO AMPLIFIER ос GHD | ® OFF AC POWE EMI FILTER INPUT POWER SUPPLY PRE-AMP +V +V ZERO ONTR C OL | PEBAL- SERVO | MCE 6 — — MOTOR | POT | у | | I | = SPAN No | CONTRO!

Therefore, the procedures presented here will be as simple, clear and brief as possible. For special problems, we recommend that you contact the factory. CHART RECORDER POWER SUPPLY There are no calibration adjustments in the power supply. Barring failure, the reference voltages will remain constant and stable. CHART DRIVE SYSTEM The stepper drive printed circuit board has no calibration adjustments. Barring failure or gear binding. the stepper drive printed circuit board and stepper motor should give many years of reliable service. If a problem should arise, consult you factory service department. PEN DRIVE SYSTEM The calibrations covered in this section should be performed by a qualified technician. The technician must have knowledge of working around voltages which may cause an electrical shock. NOTE: Gain, offset and span must be adjusted for each channel in multi-pen units. 1. Gain (See Figure 7) The gain adjustment controls the servo loop gain or "dead band” of the recorder. This can be reached through a hole in the bottom of the recorder marked GAIN. If set too high, the pen will “buzz”. If set too low, the pen will be sluggish. To Calibrate: A Short (+) and (=) inputs. (red and black connectors on back of recorder) and set pen to center scale by turning the zero control. B. Adjust gain control clockwise until pen “buzzes”, then back off counterclockwise until buzzing stops. С. Recheck the adjustment by moving the pen cover full scale using the zero control. If pen “buzzes” at any point, turn gain control counterclockwise until the -15- \ | (©) BOTTOM COVER MOUNTING SCREWS NT] Зее. | “ен FE сн me UPPER CHANNEL I 1 RN E | | 500mV/1/2/5 VOLT RANGE CALIBRATION POTS | Г те. | & оне «MIDDLE CHANNEL 4 | вы 1 NT EN ! \ UPPER MIDDLE LOWER Cao. | РЕМ РЕМ РЕМ “т Зее E a. 1 LOWER CHANNEL O “ O O I O | SPAN SPAN SPAN \_ El O O O | GAIN GAIN GAIN | | i | A !

Offset This adjustment reduces the zero shift between input spans to a minimum value. Performance of this adjustment requires the recorder input to be switched between a short circuit and a 50K ohm resistor. Connect a 50K resistor across the recorders input binding posts (+ and -). 2.1 Recorders with REC/STBY switch A. Allow the recorder to warm up to operating temperature (30 minutes is suggested). | B. Remove the bottom panel of the recorder. C. Place the REC/STBY switch in STBY. D. Place the range (span) switch in the 100mV setting (10mV setting on 2 range instruments). E. Use the Zero adjust knob to set the pen to mid-scale. F. Switch the range switch to the ImV position. G. Retum the pen to the setting in step “E” with the E potentiometer in the pre- amp circult. H. Place the REC/STBY switch in REC. |. Return the pen to the setting in step “E” with the 1 potentiometer in the pre- amp circuit, J. These adjustments are interactive so it will be necessary to repeat steps "C” through “1” until minimum pen movement is achieved. K. Remove the 50K resistor. 3. Span (See Figure 7) This enables the technician to adjust the recorder so that a calibrated full scale input signal will move the pen up to the full width of the chart. The first span adjustment can be reached through a hole in the bottom of the recorder marked SPAN. The second span adjustment is normally not necessary and the bottom panel must be removed to gain access to this adjustment. To Calibrate: A. Allow recorder to warm up to operating temperature (30 minutes is suggested.) B. Set recorder in ImV position and signal source to zero output. C. Carefully set pen to zero by turning zero control -17- D. Apply a 0.1% accuracy 1mV DC signal to the input E, Insert a screwdriver in the hole in bottom of recorder marked SPAN. Move adjustment until pen is at 100% posttion. F, Check all input spans with proper inputs for 100% +0.5% deflection. Check zero all ranges and reset as necessary. NOTE: If spans for ranges from 200mV through 5V DO NOT deflect 100% +0.5%, continue with the following steps: G. Remove the bottom panel and set the range (span) switch to the 1V position, Check zero and reset as necessary. H. Applya 1V0.1% accuracy DC signal to the input. | Adjust the 500 mV/1/2/5V range calibration potentiometer located on PreAmp PCB (See Figure 7) for 100% +0.5% pen deflection. J. Check all inputs from 200mV to 5V with proper inputs for 100% +0.5% pen deflection. There are no additional calibration points on the recorder. -18- PAPER RELEASE CLUTCH (**) Your recorder is equipped with a sprocket release that enables you to advance or rewind the paper manually. To operate the sprocket release: Lift pen lever to the full UP position. The paper may now be moved forward or backward as desired. To re-engage the chart drive: Return the pen lift lever to the full DOWN position. NOTE: After manual advancement or rewind there may be some delay, depending on the chart speed selected. until the gears re-engage. then the chart will run at the selected speed. REMOTE CHART PROGRAMMING /TTL (**) The recorder chart drive system is designed to operate from an external frequency source (including TTL levels). The chart can be run at time rate other than those built into the recorder. This mode is obtained by placing the Remote-Local slide switch, on the rear panel of the recorder, in the "REMOTE" position, and applying a pulse train, with the following characteristics, to pins 6 and 7 of the remote control connector, pin 7 being common. PULSE TRAIN SPECIFICATIONS; O/LOW state voltage +0.5V or less 1/HIGH state voltage +3V to 10V maximum Minimum pulse width: 100 microseconds Pulse frequencies up to 10KHz may be used. providing the chart speed selector is set to limit actual chart movement to 50 cm/min or less. A 50 cm/min paper speed can te obtained by applying a 500Hz external frequency and setting the char selector switch in the 30 cm/min position. The formula is Chart Speed = F Hz x S 300 Where: F = external frequency in Hz S = Selected chart speed When the external frequency is set to 300Hz, the chart drive wil run af the speeds marked on the top panel selector switch. EXAMPLE: The selector switch is set at 30 cm/min and the external frequency changed to 330Hz (a 10% increase). The chart will how run at 33 cm/min. -“Standarg on all model! 500 recorders. NOTE: Changes of external frequency offects all selector speeds by the same factor. The recommended maximum chart speed for start-stop operation is 50 cm/min. If the frequency is “swept” (no start-stop), it is possible to run faster than 50 cm/min; however, sweep rates must be gradual enough to assure accurate mechanical tracking. (**) Standard on all Model 500 Recorders. -20- OPERATIONAL TIPS AND MAINTENANCE Chart paper and pens have been carefully matched for optimum writing and minimum “bleed”. Substitutions could cause improper writing. Keep pen tips covered when not in use to prolong writing life. NOTE: If the penis left uncapped for long periods and dries out, it may be revitalized by dipping in water for a few seconds. Do not press down or otherwise manually force the paper hold down bracket. This could cause pinching of the paper as it feeds over the sprockets. Firm tension on paper roll and correct alignment of paper hold down bracket are required for proper chart paper feed. Allow recorder to warm up for about 30 minutes if high accuracy/stability recording is desired. The exterior surfaces of the recorder should be cleaned periodically by wiping with a soft damp cloth. Water may be used to remove ink, etc.; however, solvents should nat be used as they may damage or destroy the finish. -21- The modularity and simplicit in many cases.
