SECTION 1 -- OPERATION

1--1 INTRODUCTION

This manual provides installation, operation and maintenance information for the Life Line regulators and Medical

Grade PC units. A detailed description of each product is provided in the following subsections.

All components used are of the highest quality and specifically selected to achieve the highest level of performance.

These units are UL listed and conform to National Electric Code (NEC) and Occupational Safety and Health Act

(OSHA) standards.

The Life Line regulators and Medical Grade PC have tapped electronic voltage regulators. Six taps are on each primary winding of the transformer. Each tap is controlled by a silicon---controlled rectifier (SCR) switch and can become active at any time. Input line---to---line voltage and line current are monitored for each phase. Peak voltage is compared with a desired reference. Depending on this comparison, the regulation logic activates the proper SCR switch when the phase current becomes zero. This changes the primary---to---secondary turns ratio which corrects output voltage to the desired nominal. The correction process starts in less than one cycle. See Illustration 1---1.

1--2 BENEFITS

The Life Line Regulators and Medical Power PC protect electronic equipment from an overvoltage condition during line power surges and an undervoltage condition during sags. In addition, the unit protects equipment load by attenuating transients present on utility power lines. overvoltage, overcurrent, and transient conditions stress electronic components and decrease system reliability.

In medical applications, voltage fluctuations affect the image quality of imaging systems. Artifacts are introduced under sag conditions. Regulating power maintains image quality, resulting in more consistent images.

1--3 TRANSFORMER

The transformer contained in the unit is designed for convection cooling by means of free circulation of air through the bottom, front and back of the unit. Maximum ambient temperatures should not exceed 104˚F (40˚C). The transformer contains built---in thermal sensors which monitor internal temperatures. In models with a Input Main Circuit breaker (IMCB), the thermal sensors send a shunt trip signal to the IMCB in the event of an over temperature condition.

1--4 PRODUCT FEATURES

Sections 1---4 and 1---5 describe the features of the Life Line Regulators and Medical Power PC. Some features described in Section 1---4 are standard on all models while other features are offered as options. Refer to Table 1---1 to determine if the features described in this section are applicable to your unit. Refer to Section 4, Options, for information on optional features.

1--4--1 Bypass Switch

The bypass switch is located on the front panel. See Illustrations 1---4 thru 1---7. This switch bypasses voltage regulation but maintains the functioning of the voltage change/isolation transformer between input and output. In

AUTO position line to---neutral voltages are regulated. In MAN (manual) position, regulation logic is bypassed and input power is applied to load via transformer without regulation. Select the MAN position if there is a problem with regulation logic circuitry. Refer to Section 1---7---2, Nonregulating Condition for the procedure to operate the unit in bypass mode.

CAUTION

The Bypass Switch must never be changed with the unit powered up.

1--4--2 Main Input Circuit Breaker (IMCB)

The MAIN INPUT CIRCUIT BREAKER (IMCB) located on the front panel of the unit, is used to switch power to the unit

ON and OFF. See Illustration 1---5.

The IMCB is shunt tripped by activation of a solenoid within the breaker when remote switches or thermal switches in the main transformer sense an over temperature condition. If the IMCB is shunt tripped, refer to Section NO TAG,

Miscellaneous Problems for the reset procedure.

An optional undervoltage shunt---trip is available.

Be sure to observe ALL warnings and cautions when setting the IMCB to ON or OFF.

1--4--3 Power On Indicators

Power On Indicators are located on the front of the unit. See Illustration 1---5. There is one neon indicating light for each of the three phases. If a phase is lost, the corresponding indicator will extinguish indicating which phase is not powered.

1--4--4 Input and Output Power Terminals

Input and Output power connections are made at the terminals located beneath the transformer except the illustration 1---5 where the terminals are located above and to the rear of the main transformer. See Illustration 1---4. Terminals are labeled H1, H2, H3, or L1, L2, L3 for the input cable connections and X0, X1, X2, X3 for the output cable connections.

4--6 INPUT/OUTPUT FILTERING

The Input/Output filter comprises an input filter installed on the primary and an output filter installed on the secondary of the transformer. The input filter consists of a resistor/capacitor network which acts as a large snubber circuit to eliminate high frequency impulses from entering the power system. The output filter consists of a capacitor network which, when coupled with the primary filter, virtually eliminates most electronic noise from reaching the applied load or being fed back to the unit from noise generating loads. See Illustration 4---4 and 4---5.

GLOSSARY

Air Conditioning

The transformer used to feed a current signal to the logic board.

The hinged front door on the Medical Power PC (15 --- 75 Kva). It covers the bypass switch and the IMCB if installed.

The hinged panel behind the front door on theMedical Power PC (15 --- 75 kVA) into which the bypass switch and the IMCB (if installed) are mounted.

InputMain Circuit Breaker — The circuit breaker on the front panel used to switch power to the CP 18 ON and OFF. Optional on Medical Power PC

(15 --- 75 kVA).

National Electric Code

National Electrical Manufacturers Association

Occupational Safety and Health Administration

Printed Circuit Board — A surface for the mounting and interconnection of electronic components.

Remote Emergency Power Off — A switch, separate from but wired to the regulation unit, when pressed, shunt trips the Main Input Circuit Breaker.

Thermal Remote Emergency Power Off — A thermal activated switch, separate from but wired to the regulation unit, which reacts to a predetermined temperature range by shunt tripping the Main Input Circuit Breaker.

Snap the breaker first to OFF position, then to ON.

Silicon---Controlled Rectifier

A device for tripping a circuit breaker indirectly, using a signal to activate a solenoid, instead of directly, because of an overcurrent condition.

A circuit breaker in an open position as a result of an overcurrent condition to the load, or as the result of a remote trip command (shunt trip). In a tripped condition, power to the load is off. The tripped circuit breaker position differs from the off position in that the breaker must first be turned to the off position before restoring power to the load.
