1 1 Installation Rec ommendations Proper Wire Si zing • As a minimum, always siz e wire gauges a s specified b y the National Electrical Code (NE C) for electronic con- trol devic es.
12 V oltage Source • Connecting the Vilter Vission 20/20 to breake r panels and centr al control transforme rs exposes the Vission 20/20 to large amounts of electromagnetic inte r fere nce (EMI) emitted from the other devices connected to the second ar y terminals of the tr ansformer .
13 Grounding • Continuou s grounds must be run from the po wer c ompany gr ound to the Vission 20/20. • Grounds must be c opper or aluminum wire .
14 Mixing V oltages • Separ ate diff eren t voltagesfrom e ach othe r and separate A C from DC. • Each voltage lev el mu st be run in separa te conduit: • 460 V AC • 230 V AC •.
15 Wiring Methods • Don’t “D aisy-Chain ” contr ol powe r for Vission 20/20 pane ls..
16 DO: • K eep AC wires aw ay from circ uit boards. • Alwa ys run conduit into the bott om or sides of an enclosure . • If the conduit must be placed in the top of an enclosure , use a water -tight conduit fit - ting to k eep water from ent ering the enclosure .
17 Vission 20/20 Architecture The Vission 20/20 contr ol panel utili zes X -86 PC technology with a Linux Operating syste m. The V ission 20/20 has the f ollowing attributes : • Low pow er , Industri al rated X -86 CPU. • 15” XGA , high resolution L CD display .

24 Main Screen The main screen gives the operator an ove rall view of operating parameters affecting the compressor package. This screen is display ed when mainten ance items and set -points items are not being per formed. The data on the screen is c ontinuously upd ated.
25 L OG ON BUT TON Navig ates to the log on scree n which allo ws the ope rator t o ha ve acc ess t o system set -points, based on his le vel of security . LANGU AGE BUTTON Selects the prefe rred language f or all screens. HELP BUTTON Provide s help file not es for v arious screens and s ettings.
26 COMP RESSOR CONTR OL - Na vigat es to the c ompressor contr ol screen where the ope rator can set the variou scom - pressor c ontrol parame ters. ALARMS AND TRIPS - Naviga tes to the alarms and trips screen w here the operator can set the various alarm and trip paramete r s.
27 SLIDE CALIBRA TION - Navig ates to the slide calibration screen where the operat or can calibrate the slide and volume actuators. TREND CHART - Navig ates to the tre nd ch ar t screen where the operat or can select up to four paramete r s for histori- cal data trend ing.
28 This screen allo ws the operat or to view and adjust s ettings tha t affect compres sor capacity control. COMPRESS OR CONTROL • Pressure/T empera ture contr ol setpoints • Auto-c ycle c o.
29 TIME PROPORTIONING CONTR OL Assume tha t Suction Press ure is the se lected param ete r to co ntr ol c ompre sso r cap acity . Time pro portionin g co ntr ol is the method used t o control the c ompressor slide valve positi on in response to a se tpoint.
30 • 3.5 second pulse = suction pressure is in the propor tional band regi on and is > 70% and < 80% from the dead- band region. • 4 second pulse = suction pressure is in the proportional band region and is > 80% and < 90% from the dead- band region.
31 OTHER SETPOINTS THA T MIGHT BE REQUIRED FOR MO TOR PID CONTR OL • Max Change Rate = The VFD motor PID output is limited by this paramete r to preven t large instantaneous change s to the motor speed . • Dead-band = used to establish a range on eithe r side of the set -point in which no capacity con trol action will occur .
32 (For F uture Sof t ware Re leases) Pump -down • The Pump -down set -points define a method of “pumping” down a chiller , which is to draw off refrigerant from the chiller . The purpose is to preve nt liquid refrige rant from dev eloping in the chiller during an off cycle , and then being drawn into the compressor when it restar ts.
33 • Stop Delay = delays the compressor from s topping when the suc tion pressure is equal to or less than the stop pressure . • Minimum Slide Position = The minimum capacity slide position that the c ompressor is allo wed to r un at.
34 Misc. Control • Control Mode = Drop-down bo x allow s selection of current operating mode, from the list of allowable modes. • High Motor Amps (Unloading) = This contr ol fea ture will limit the c ompressor capacity whe n the c ompressor motor amps re aches these load limiting set -points.
35 • Sto p Load = pre ven ts the compre ssor from loading whe n the set -point is re ached. Set this set -point abov e nor ma l di sc har ge op er at ing con dit ion s.
36 • Current T ransformer Ratio : The value ente red must agree with the Curren t T ransforme r Ratio label on the curren t transformer being used. The current transformer is mounted in the compress or motor conduit box. The r atio is stated in te rms o f “Primary amps : Second ar y amps ”.
37 This screen allo ws the operat or to view and adjust s ettings f or compres sor safety and alarm settings. Alarms and T r ips defined are : • Low Suction Pressure set -points • High Disch.
38 • Low Suction Pressure Alarm and T rip = This is the low suction pressure safe t y . This safety is active in both tempe rature and pressure control modes. An alarm or tr ip will be ac tive on a drop in suction pressure at or below the s et -point value.
39 • Low Suction T emperature = This is the low suction tempe rature safety . The alarm or tr ip will be ac tive if the suction temper ature should drop to a value th at is at or be low the set -point value . • High Discharge T emperature : This is the high dischar ge tempe rature safe t y .
40 Pre-lube Oi l Pressure = This is the pre-lube oil pump failure saf ety. If the pre-lube oil pre ssure does not rise abov e the alarm setting f or a time exc eeding the Minimum Pre-lube Time and the pump run runs longer than the Pre-lube Pump Time Limit, an alarm or trip will occur .
41 This screen allo ws the operat or to view and adjust time r settings assoc iated with c ompressor operation. Timers defined are : • Capacity Increase S tar t Delay • Minimum Compressor Pr.
42 • Low Oil Pressure Safet y Changeov er = This is the length of time in which the normal Low (Run) Oil Pressure set -points will be mas saged by the values of the Pre lube Oil Pressure set -points. Af ter the timer has expired, the normal Low Oil Pre ssure set -points become active .
43 • T rue Anti-R ec yc le Timer = Once the compre ssor turns off , this timer will ke ep the compre ssor o ff for the settin g of the T rue Anti -Recycle Time r . This timer is used t o preve nt short c ycling of the c ompressor . • Accumulativ e Anti-Recycle Tim er = This timer also f orces a specified time bet ween compress or star ts.
44 This screen allo ws the operat or to forc e digital outputs ON for di agnostic purpose s. If yo u choo se to exit this menu while an output is still for ced on, the output will be “unf orc ed” be fore the menu exits.

47 button in the ce nter of the photo chopper to release the brake , and thereby release the tension on the ac tuator motor . Then use the “+” button to pulse the mo tor so that the capacity slide is “just off” of its minimum position and there is no te nsion on the motor shaft.
48 NO TES: The manual operating shaft on the gear motor should be turned the opposite direction of the desired comm and shaft rotation. The capacity and volume control motors are equipped with a brake , if it is necessar y to opera te the con trol mo tors manu ally , the brak e must be dise ngaged.
49 Slide V alve Operation The slide valve actuat or is a gear -motor with a po si- tion sensor . The motor is powered in the for ward and reverse directions from the main comput er in the con trol pane l. The position se nsor te lls the main comput er the position of the slide valve .
