Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
1.0 Introduction
1.1 Mains supply wiring
THREE PHASE OPERATION ("NORMAL"): In Australia the HP12-TR / HP12-SC is normally fitted with a flexible supply cable and
32 amp Clipsal plug. The cable has 6mm2 (40 amp) conductors for t he three phases, t he neutral and the earth.
Th e 3 2 a mp Clip s a l p lug s u its the ma jor ity of 3 phase v e n u e outlets in Au s tr a lia , and w ill provide sufficient power to run twelve pairs of 1000 watt PAR64 lamps, assumimg normal duty cycles.
The incoming mains supply must be protected at not more than 50 amps. The d imme r s ' circuit breakers are not rat ed t o co rrect ly clear faults if the supply protect ion is in excess of this. Mains supplies are generally protect ed at lower cur rents (32 amps or 40 amps at most Australian venues). It is up to the user to ensure that the dimmer is used in a manner that do es not exceed the available supply capacity.
In Australia the HP6-C is normally fitted with a flexible supply cable and 50 amp Clipsal plug. The incoming mains supply must be protected at not more than 63 amps. The dimme r ’ s c ircu it br e a k e rs are not r ate d t o corre c tly cle a r fau lts if t h e s upply protection is in excess of this.
The power cable is t erminated wit hin the dimmer at a six-way terminal block and an earthing stud. The six-way terminal block has three poles for t he three live mains phases (labelled A1, A2, A3), and three poles for the mains neutral (N1, N2, N3). The three neutral poles are bridged with a copper link, with the mains neutral connected t o terminal N2.
If the supply cable is damaged, it must be replaced with a cable available from JANDS or its service agents.
SINGLE PHASE OPERATION: The dimmers may be configured for single phase operation where three phase mains
supply is unavailable. The dimme r sho uld be supplied with three same-phase actives and three neutrals. The
three active lines must each be prot ected at not more t han 50 amps [63 amps: HP6-C]. The three neutral conductors must each be rated at t he same current as the actives. The ea rt h conductor should be similarly rated.
The bridge between the three neutral terminal poles (N1, N2, N3) must be removed before the three incoming neutral lines are connected.
Although it is possible to supply the dimmer with one large single phase feed, the dimmers' br eakers ar e not ra ted to clear fault s if the supply is protected at currents of over 50 amps [63 amps: HP6-C].
Th e ne u t r al- e a r t h d et e c t io n will ac t if all t h r ee ne u t r a ls h av e mo r e t h an 15 v o lt s to e ar t h , or if any one neutral has more than 45 volts to earth.
Equipment Description 1-2
Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
DELTA SUPPLY OPERATION (ILLEGAL IN MOST COUNTRI E S !) The available venue mains supply in some countries (eg. the Philip p ine s ) is in the fo rm o f
three phases (220 volts between phases) with no neutral connection. The dimmer ma y b e configured for operation from 220V delta supplies.
The bridge between the three neutral terminal poles (N1, N2, N3) must be removed before the three incoming active lines are connected.
The first incoming active is connected to terminals A1 and N3.
The second incoming active is connected to t er minals A2 and N1.
The third incoming active is connected to terminals A3 and N2.
Note that this connection is ILLEGA L in Australia , Europe and the U.K.. Note that this connection renders the output sockets' neutral pins LIVE. Note that a dimmer wired in this fashion will be subjected to CONTINUOUS
OVERVOLTAGE if connected to the 415V wye or star three-phase supply of most countries.
The three active lines must each be protected at not more than 50 amps [63 amps: HP6­C]. The dimmers' breakers are not rated to clear faults if the supply is protected at currents of over 50 amps [63 amps: HP6-C]. The earth conductor must be similarly rated.
Th e neut ra l-ea rt h volt ag e de tec to r w ill sens e whe the r t he "c ent re" (av era ge) volt ag e of the three phases deviates more than 15 volts from earth.
Once again ­DELTA CONNECTION IS ILLEGAL AND DANGEROUS IN MOST COUNTRIE S !
1.2 Phase failure
If o n e p o w e r ph as e s hould fa il, t he d immer w ill t u r n o ff t h e o u t p u t s a ss o c iat e d w it h t ha t phase. This function can be disabled by the operator. See section 4.1.4.5.
1.3 Circuit breakers
Th e circuit breakers protect the HP dimmers' o ut put devices a nd the user’s o utput wiring against overloads and short circuits. The breakers have a "type 32" delay characteristic, which is s imilar to standard switchboard b rea kers.
The delay characteristics of the circuit breaker are a delicate balance between high speed (required for adequate semiconductor pr o tect ion) and surge tolerance (to pass t he inrush current demanded by large incandescent lamps).
Each of the twelve output circuits is protected by a 11.5 amp [25 amp: HP6-C] fast­acting magnetic circuit breaker. These breakers are designed to pass the rated current, but will d is c onne c t t h e outpu t circu it fo r a n y overlo a d c ond itio n (th e la rge r th e ove r load , the quicker the disconnection).
NOTE: The dimmer outlet sockets are rated at 10 amps [20 amps: HP6-C]. Avoid loading the dimmer outputs beyond the socket capa city.
The breakers protect the dimmer’s output devices from short-circuit loads and faulty wiring loo ms, a nd save on expen sive dimmer repairs. A tr ipped circu it breaker indicates a load fa ult tha t r equ ires immediate atten tion.
Equipment Description 1-3
Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
1.3.1 Overloads and Inrush
Co ld lamp fila me n ts c onsu me con s id e rably mor e p owe r th a n w a rm filame nts. Th is me a n s that the first time the lamp is turned on to full, the surge current can be several times greater than the rated cur r ent for the lamp.
This cold surge current may be enough to trip the output circuit breakers. If this “nu isa nc e - t r ipp in g” o f t he c ir cu it b r ea k er s is a p r o ble m, t h e fila me nt P r e he at fa c ilit y ma y be utilised . See section 4.1.4 .5 for inst ructions on e nabling the Preheat fac ility.
Lamp filament resistance is roughly propo rt ional to temperatur e. A filament preheated to 900°K (630°C) has a resistance about three times higher than a filament at room temperature (300°K, 30°C).
Preheat turns on the selected channels a very small amount (around 1% at 240 volts and 4% at 110 volts) which heats the lamp filaments and increases their electrical resistance. When the lamp is then turned on full, the surge current is much less and the circuit br eak er will not trip .
Other advantages of using Preheat are an increase in lamp life (due to the reduction of thermal shock to the filament s), and a reduct ion of lamp heat up t ime (the lamps will flas h sligh tly quick er).
1.3.2 Short Circuits
The SCRs and triacs are protected by the circuit breakers during shorts produced by damaged wiring or blown lamp filament fragments across the filament supports.
The stress on SCRs and triacs during short circuits depends on:
The operating temperature of the devices prior to application of the short
The impedances of the mains supply, dimmer cho kes and output cables
The let-through energy of the circuit breaker when breaking the fault
The moment during the mains wavefor m when the sho rt is ap plied
Th e t r ia c s in t he H P1 2 - T R w ill s u rv ive o u t p ut s ho r t cir c u it s u nd e r mo s t c o nd it io n s. T he more rugged SCR pairs in the HP12-SC, aided by higher choke impedance, will sur vive output short s under extreme conditions (high operating temperatures, high supply fault curr ent ava ilability, zero cable le ngth from dimmer to short ).
1.4 Outdoor Systems
It is recommended that at outdoor shows where the power is locally generated the following steps be taken to ensure a trouble-free show:
1. Run the console from an extension cord that is plugged into t he same power
so ur ce as t he dimme rs. If t his is n ot po ssible a DMX iso latin g unit sho uld be inserted between t he ligh ting console and the dimmers.
2. Disable the neutral detect system. Generators often have poor regulation on
their output power and it is very likely that under certain circumstances this can cause the neutral detect feature t o trip.

1. Channel output circuit breakers: The circuit breakers are rated at 11.5 amps continuous, however Jands recommend the maximum load connected to a channel be limit ed t o 1 0 a mps . T he H P6 - C br e ak e r s a r e r a t e d at 25 a mp s b ut J a nd s r ec o mme nd the maximum channel lo ad be limited to 20 amps. If nuisance tripping occur s, enable the Preheat option (see section 4.1.4.5). See also section 5.6 for a full explanation of nuisance tripping.
2. Display: A r ed four dig it alp ha- numer ic dis play is use d to sh ow dimmer st at us a nd option menus.
3. LEVEL/FUNCTION encoder wheel: This detent action control knob is used to select items from the menus, and to select the channel levels or chase rat e (depending on the operat ing mode).
4. DMX IN/LOOP connectors: A standard five pin AXR connector inputs control desk DMX-512 signals and outputs them to ot her dimme rs via t he Lo o p c o nne ct o r. S ee section 8.2 for wiring details.
5. DMX IN LED: A green LED indicates the presence of DMX signals.
6. Keypad: These switches are used to select different opt ions and operating modes. A
red LED is associated with each switch to indicate activation of selected function.
7. PHASE LEDs: T hree green LEDs (one for each phase) indicate that the three phase mains supply is available.
8. Channel SELECT switch: These select or deselect options for each channel, or switch a chan nel bet ween “on-line ” and “o ff-line”. I f a cha nnel is “off-line”, it will not respond to the DMX input signals.
9. Channel STATUS LED: A bi-colour LED indicates channel status, ie.
Red = channel set for 110V o utput Green = channel set for 240V output Off = channel disabled Orange = voltage change selected but not yet confirmed Flashing = channel selected for changes to be made
10. DRIVE LED: This green LED indicates a contr ol signal is being applied to that channel.

11. LOAD LED: This red LED serves two functions. In normal operation, it acts as an output mimic. When the channel drive is at zero, it indicates whether that channel’s load is disconnected (or o pen-circuit).
To check a load, set t he channel drive to zero. The LOAD LE D w ill t u r n O N if t he r e is no lo a d.
For levels above zero, the LOAD L ED w ill mimic the c ha n n e l outpu t wh e never a load is connected.
Note that the channel circuit breaker must be ON for the LOAD LED circuitry to work.

3.0 Circuit Descriptions
(
Figure 3.1
The Output PCB contains the circuitry for the output devices (triacs in the HP12-TR and SCRs in the HP12-SC and HP6-C), the temperature-controlled fan, and the 15 volt power supply.
3.1 Mains and Low Voltage power supplies
Th e d imme r ele c t r o nic s us e s lo w volt a ge d c p o w e r at 15 volt s (u n re g u lated ) a nd 5 v o lt s (regulated). The HP12-SC also uses a 10V regulated supply for the gate drive os cillators. The unregu la ted DC p owe r is s upplied by three transformers mounted on the output PCB.
3.1.1 Mains Circuit Wiring:
The mains circuits of the HP dimmers are co nfigur ed as three separate phase circuits, with four channels per circuit. The three active mains inputs and three separat e mains neutral inputs appear at a terminal block, labelled A1, A2, A3 and N1, N2, N3 respectively. The ground ter minal is an adjacent M4 stud.
This wiring allows the dimmer to be configured for three-phase star (wye) mains supplies, three-phase delta supplies or single-phase supplies.
THREE PHASE OPERATION ("NORMAL"): Th e r ac k mo u nt HP dimme rs ar e no rma lly supplied with a three-phase power cable and
plug attached, suiting the vast majority of available mains supplies (ie. three phase and neutral). The three live mains phases are connected to terminals A1, A2, A3. The three neutral poles are bridged with a copper link, with the mains neutral connected t o terminal A2.
SINGLE PHASE OPERATION: The dimmers may be configured for single phase operation where three phase mains
supply is unavailable. The dimme r sho uld be supplied with three same-phase actives and three neutrals. The
three active lines must each be prot ected at not more t han 50 amps [63 amps: HP6-C]. The three neutral conductors must each be rated at t he same current as the actives. The ea rt h conductor should be similarly rated.
The bridge between the three neutral terminal poles (N1, N2, N3) must be removed before the three incoming neutral lines are connected to these terminals. The three incoming actives are connected t o A1, A2, A3.
Equipment Description 3-2
Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
DELTA SUPPLY OPERATION (ILLEGAL IN MOST COUNTRI E S !) The available venue mains supply in some countries (eg. the Phillip in es ) is in t he fo r m o f
three phases (220 volts between phases) with no neutral connection. The dimmer ma y b e configured for operation from 220V delta supplies.
The bridge between the three neutral terminal poles (N1, N2, N3) must be removed before the three incoming active lines are connected.
The first incoming active is connected to terminals A1 and N3.
The second incoming active is connected to t er minals A2 and N1.
The third incoming active is connected to terminals A3 and N2.
Note that this connection is ILLEGAL in Australia, Europe and the U.K. since this connection renders the out put sockets' neutral pins LIVE.
No te t hat a dimme r wire d in this fas hion w ill be sub jected t o CONT INUOUS OVER­VOLTAGE if connected to the 415V wye or star three-phase supply of most countries.
3.1.2 Mains Radio Frequency Suppression
Radio-frequency interference generated by phase-controlled dimming is heavily attenuat ed before it can contaminate the mains supply.
Capacitors C1, C2 and C3 (1uF 275VAC X2 rated) are connected from each incoming active (A1, A2, A3) to the corresponding neutral (N1, N2, N3).
Capacitors C14 thru C19 (4700pF 275VAC Y2 rated) are co nnected from each incoming active and neutral to ground.
The mains circuits are protected from (improbable) catastrophic failure of these capacitors by fusible PCB track links (labelled FL1 thru FL4). Failure of these links will remove power from the low-voltage transformer associated with that phase. The links may be re new ed du ring rep airs by wir e links (a s ingle s tr and o f flexib le wir e, n ot mor e than 0.2mm dia).
3.1.3 Neutral - Earth Voltage Detection
Voltages of more than 15V (AC average) between neutral and earth are a strong indicator of mains supply problems (eg missing or weak neutral connection, or missing earth).
Th e vo ltage from the dimmer s' ea rt h to each of the three neutrals is sensed by three 100K resistors (RG1, RG2, RG3), full-wave rectified and fed to the input LED of an optoisolator.
When the dimmer is configured for normal three-phase star connection, the three incoming neutrals are bridged, yielding an impedance of 33K from neutral to gro und and a sensitivity of 15V AC average.
If t h e d imme r is c o nf igu r e d fo r t h r ee s ame - p ha se inp u t s, each neutral has a sensitivity of 45V (or 15V for all three neutrals).
If the d imme r is c onfig u r ed for d e lta ope ratio n (with no incoming neutra l) th e c ircu it will detect when the "centre average" of the three phases deviates more than 15V from earth.

Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
3.1.4 Low Voltage Transformers
HP12-TR: The transformers are nominally rated at 375V (primary), 23V (secondary). Th e p rima ry w ind ings o f t hes e t r an sfo rme r s w ill to le ra t e 415 vo lts without o verheating. They are protected against secondary-side overloads by card-mounted 30mA PTC thermistors. These thermistors are sized NOT to trip during mains overvoltages, but WIL L tr ip if a lo w vo lta ge fa ult o cc urs . T hermis to r c uto ut will t ur n off the fro ntp anel PHASE LED.
HP12-SC, HP6-C: The transformers are nominally rated at 240V (primary), 15V (secondary). The primary windings are protected against secondary-side overloads by card-mounted 30mA PTC thermistors. These thermistors will trip during continuous mains overvoltages of more than 340V. Thermistor cutout will turn off the frontpanel PHASE LED.
If t her mist or c ut ou t o ccu rs, the y may be r ese t by t ur ning off p owe r t o the dimmer for five seconds. However, since thermistor cutout will never occur during normal operat ion, t he cause o f cutout should be investigated.
3.1.5 Control Tone Rejection
Control to nes are superimposed on mains voltages by supply authorities to co ntrol off­peak heaters etc. Tone frequencies of 750 Hz and 1050 Hz are common, although frequencies from 167 Hz to 1750 Hz are in use. Amplitudes are typically less than 5 volts, although higher levels have been reported at some locations.
These tones may cause flicker in dimmed lamps, due to jitter in the detected zero­crossing position.
Th e e ffe c t o f c ontrol t ones is min imis e d b y filter in g a t t h e s e c ondary w in d in g s o f the low voltage transformers. Resistor-capacitor networks (R1-CF3, R2-CF4, R3-CF5), in conjunction with inherent transformer inductances, form a 12 dB/oct filter at 400 Hz. Control tones at levels up to 15 volts at 750 Hz, or 25 volts at 1050 Hz, have little effect on performance.
3.1.6 Low Voltage DC Supplies
Each of the three tr ansformers has two asso ciated rect ifiers. One set o f rectifiers feeds the common DC supply filter capacitors, while the other provides full-wave rectified waveforms to the zero- crossing detect ors and three phase indicator LEDs via the Front Panel PCB.
Th e dimme rs’ u nre gula ted supply is filtered by C9 (2200uF) and directly feeds the fan controller, the overvoltage detector and the temperature sensors. All other circuits are supplied via the OTEMP overtemperature cut out.
Th e dimme r w ill shut d ow n und er so ftw are co nt ro l at 8 5°C. If t he d immer ma nag es t o reach higher temperatures than this, the OTEMP cutout will remove power from all cir cu it s e xce p t t h e fa n c o ntroller a nd a ss o cia t e d cir c u it s. T he fa n s pe e d w ill in cr e a se d u e to lighter supply loading.
The unregulated dc voltage at the common supply filter capacitor (C9) is normally ar oun d 1 4 ~ 1 5 v olt s b u t may drop a s low a s 1 1 vo lts w ith lo w mains v olta ges , or rise in excess of 20V during severe mains overvoltages.
Mains overvoltages are sensed as high unregulated DC voltages by op-amp U1b. Since the DC supply voltage is dependent on dimme r lo a d ing as w ell a s main s v o lt a ge , t h e t r ip point of this circuit may vary from 260V to 280V AC mains voltage.
Equipment Description 3-4
Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
3.1.7 Fan Control
Temperatures are sensed by LM35DZ sensors mounted at the exhaust ("hot") ends of the heatsinks. These sensors have an output voltage of 10mV per degree Celsius (ie. 300mV at 30°C). Their output voltage is summed and fed to the frontpanel CPU card for temperature display, and to the 12 volt dc fan control.
The fan speed controller is a DC amplifier formed by op-amp U1a and transistor Q1. The fan is "held off" until sensor temperatures reach 30°C by resistor R16 from the 5V rail. The fan voltage reaches 12V at t emperatur es of 50°C.
The circuit is protected against shorts in the fan or its wires by transistor Q2, which clamps the out put current at 0.6 amps.
3.2 Phase control
Th e p ow er a pp lied t o a lo ad is va r ied by co nt r o lling t h e p oin t o f t hyr ist o r firin g in each mains half-cycle.
The convention used here is that firing angles of 0° (0 radians) occurs at t he end of each half cycle, and give zero output. Firing angles of 180° (π radians) occurs at the beginning of each half cycle, giving maximum (unity) output.
The traditional method of achieving phase control (ie. firing position control) has been to generate a "ramp" voltage in each half-cycle, which is then compared t o t he dc contro l signal.
Key elements in this technique are:
The ramp begins just after the st art of the half cycle, at a voltage equal to the
maximum control voltage.
The ramp ends just before the finish of the half cycle, at a voltage equal to the
minimum control v oltage.
The beginning and end of the ramp are determined by zero crossings of the
mains wav eform.
The shape of the ramp determines the control law (CV to P law).
No t e t h at the finit e wid t h o f t he z er o - c r o s sing p u lse c au s es t he d immer t o jump fr om no firing to some small firing angle as soon as contro l voltage is applied. The snap-on firing angle is defined by the zero cro ssing pulse width.
This is actually a ver y mino r pr oblem since zero c rossing puls es o f 2.2 ms (±1100 µs around tr ue zero crossing) give a snap-on power o f less than 1%. The HP has a zero­crossing pulse width less than 2 ms.
The HP micropro cessor (µP) generat es its "ramp" digitally, and specifically shapes the ramp to pro vide linear control-to-power characteristics. The µP then compares the DMX channel information with the generated ramp information and turns on the appro priate output device at the required point on each mains half-cycle.
3.3 SCRs and triggering circuits
HP12-TR: The triacs used in the HP12-TR are 40 amp, 600 volt devices (type Q6040K) with 2500
volt isolation to t he mounting tab. They have a surge current rat ing of 335 amps for 10 millise cond s. The d immer w ill func tio n wit h re placement triacs of lower ratings but its ability to s urv ive shor t circuits and ove rvoltages will be jeopardised.
Equipment Description 3-5
Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
The output devices are triggered with Siemens BRT12 opto-isolators. These are optically triggered SCRs rated at 600 volts.
Opto-triggered dimmers have a lower ability to correctly drive low-power inductive loads than DC-fired SCR dimmers. Although this is true of the HP12-TR, careful snu bber des ign and comp one nt se lect ion guar ant ees tha t it will co rr ect ly dr ive a ll load s from rated maximum down to 25 watt transformer pinspots.
When the lamp blows in a transformer-driven pinspot, the unloaded t ransformer primary pr es ent s a ve ry s mall, hig hly ind uc t ive lo a d. T he H P1 2 -T R d immer may mis be hav e w ith such a lo ad. However, if two o r mor e pins pot s are connec ted to a dimmer channel, a lamp failure in one pinspot will have n o adverse effects.
HP12-SC/HP6-C: The SCRs used in the HP12-SC are 35 amp, 600 volt devices (type S6035K) with 2500
volt isolation to t he mounting tab. They have a surge current rat ing of 425 amps for 10 millise cond s. The d immer w ill func tio n wit h rep lacement SCRs of lower rat ings but its ability to s urv ive shor t circuits and ove rvoltages will be jeopardised.
The SCRs used in the HP6-C are 65 amp, 600 volt devices (type S6065) with 2500 volt isolation to the mounting tab. They have a surge current rating of 800 amps for 10 millise cond s. The d immer w ill func tio n wit h rep lacement SCRs of lower rat ings but its ability to s urv ive shor t circuits and ove rvoltages will be jeopardised.
The SCRs are connected in back-to-back pairs, such that during each mains half-cycle one SCR is b locking (re verse biased) and the oth er will co nduct if trigge red.
HP12-SC: The SCR gates are triggered with continuous DC (as opposed to trains of pulses), which forces the SCRs to conduct even if the load current is lower than the SCR latchin g curr ent. This a llows exc ellent control over small an d highly inductive load s.
The DC gate firing current for the twelve SCR pairs is provided by twelve power os cilla to rs . T he 40kHz po wer oscillat or s o pe rat e fr o m a 1 0V reg ula te d supply, and are contro lled by phase-control signals from the CPU.
The oscillator outputs drive pulse transformers. The two secondary (mains-side) windings of the pulse transformers are full-wave rectified and fed to the SCR gates. Sufficient gate current is generated to correctly trigger the SCRs at very low temperatures (minus 10°C).
Ea ch o f the tw elve osc illat or s is pro t ec te d by a 2R7 supply resistor, such that failure in an o s cilla t o r fu se s t he r es isto r witho u t d isr u p t ing o t h er o s c illat or s. E a ch o sc illa t o r d ra w s 8mA when inactive, and around 80mA when that channel is driven to full.
HP6-C: The SCR gates are triggered with Siemens BRT12 opto-isolators. These are optically triggered SCRs rated at 600 volts.
Op to - tr ig g e red S C R dimme rs ha ve a low e r ab ility to correc tly drive low-powe r in d u ctiv e loa ds tha n DC -fir ed SCR dimme rs.

When the lamp blows in a transformer-driven pinspot, the unloaded t ransformer primary presents a very small, highly induct ive load. The HP6-C dimmer may misbehave with such a lo ad. However, if two o r mor e pins pot s are connec ted to a dimmer channel, a lamp failure in one pinspot will have n o adverse effects.

3.4 Output chokes and filtering
Th e chokes and filters minimise the emission of high frequen cy interference radiated from dimme r outpu t wires. Th e fa s t ris ing wa ve forms produ c e d b y p h a s e - c ont ro lle d tria c s a nd SCRs have large amounts of high frequency energy, which would be radiated as electromagnetic interference (EMI) without the chokes.
The degree of suppression at low frequencies (150Hz - 150kHz) is indicated by the output voltage risetime. Longer risetimes indicate superior suppression, lower acoustic noise in lamp fila ment s and less "buzz" co upled into audio wiring.
The HP12-SC chokes have a risetime of over 500 microseconds, measured from 10% to 90% of the rising waveform edge, when driving a 2500 watt incandescent load at 90° firing angle. The HP12-TR chokes have a risetime of 280 microseconds when measured in the same fa shion.
The suppression at frequencies above 150kHz must meet Australian and international standards; the HP6-C, HP12-TR and HP12-SC provide suppression superior to statut o ry requirements.
High frequency output filtering in the dimmers is provided by capacitors (CF1 thru CF12) connected from the SCR/triac hot input to t he choke out put. I n addition, snubber components RS1 thru RS12 and CS1 thru CS12 serve to reduce the amplitude of commutation transients.
NOTES: HP12-TR / HP12-SC / HP6-C Dimme r cha nnels not dr iven o n will " leak " 50 Hz AC cur ren t t hro ugh the RF-f ilter and
snubber capacitors to their loads. The HP12-TR uses 100nF snubber and filter ca p a c ito rs, an d w ill pass u p to 15mA to the load; t h e H P 12- SC u s e s 4 7 n F c a p a citor s a nd will p as s up t o 7mA . T he HP 6 - C u s es 100nF snubber and filter capacitors, and will pa ss up to 22mA to the load.

3.5 Load & drive indicators
3.5.1 Drive LEDs
Each channel's Drive LED is connected to t he same phase-contr ol signals (generated by the CPU) which trigger the HP12-TR's / HP6-C's opto-isolators or the HP12-SC's power os cillat ors . The Dr ive LE D mimics t he p hase-co ntr ol drive to the tr iacs o r SC R pa irs. The LED intensity is linearly contro lled by the duty cycle of the drive, but visually does not appear t o be linear.
3.5.2 Load LEDs
Ea c h c h a nn e l’ s L oad L E D is c onne c ted a s a n outpu t volt a g e mimic. T he Load L E D s a re op to -is olat ed fro m th e dimme r ou tp ut s. T he o pto -is olat o rs ar e d riven from t he o ut put s via a 47K resistor and bridge rectifier. The "neutral retur n" from each channels' bridge rectifier ret ur ns t o the neutral associated with that channels' phase (N1, N2 or N3).
Equipment Description 3-7
Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
The opto -isolators' output drives the Load LEDs via 470R resistors from the 5 vo lt rail at up to 6mA. Although the LED current is vaguely proportional to output voltage, visually it is not linear due to L ED and percep tual non-lin ear ities.
3.5.3 Load Detecting
Whe n no loa d is c on nec te d, the Lo ad LED will lig ht . T he snu bber a nd filt er c apa cit or s (100nF for HP12-TR and HP6-C, 47nF for HP12-SC) will p as s a n ac c ur r e nt of 7mA t o 22mA, which is sensed by the Load LED as an output voltage.
The Load LED may be used to indicate the presence of a load only when no drive is present, and the channel’s breaker is on. In this case, NO LOAD = LED ON; CHANNEL LOADED = LED OFF.
When the channel is driven (as indicated by the Drive LED) the Load LED will act simp ly as an output mimic.

Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
3.6 CPU card
(
Figure 3.2
The HP Series dimmers are fully digital. The CPU reads all inputs and generates all output s. The one exception to this is the fan control system which is intended to oper ate without CPU intervention - if the CPU were to stop operating the cooling system will continue to op er ate normally.
Many of the components on the CPU card ar e Surface Mount, and will r eq uir e e xt r eme care if components are t o be replaced at any stage.
The CPU is required to read the following inputs:
the temperature sensor
three phase voltages
all switches
the rotar y encoder
the DMX input
mains zero crossin g points
The CPU also drives the following outputs:
all LEDs
the DMX output
twelve dimmer channe l opto-isolators
3.6.1 M icroprocessor
The micropro cessor (µP) is a Motoro la 68332 (IC1) housed in a 132 pin QFP surface mount package. This is a highly integrat ed par t consisting of a 68020 core surrounded by serial ports, a system integration module, and a time processing unit which is used to contro l the triacs via the opt o-isolators. T he system integration module is configured to generate chip select lines which are used to select the peripherals. The µP’s internal clock is d erived from an external 16 M Hz c rystal oscillator (OSC1 ).
The four DIP switches (SW1) are connected directly to the unused CPU interrupt pins. During normal operation all DIP switches should be off.
3.6.2 M em or y
The CPU memory consists of a 256Kx8 program EPROM (IC10) and two 128Kx8 static RAMs (IC2, IC3). Program is copied from EPROM into RAM at boo t and subsequently executed from RAM to improve execution speed. As of September 1995, the current software version is “V1.1F”.
The EPROM may in the future be substituted with a FLASH device to allow for in-field software upgrades. Read and Write control signals are created by a 74HC00 (IC15); during normal operat ion the write pulses are not generated as they are only used when the software is being uploaded into a FLASH device. Diode D2 configures the CPU at reset to have an 8 bit boot EPROM.
Equipment Description 3-9
Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
Read and Write control lines for the SRAM are generated by the GAL16V8 (IC7). A MAX691 “watchdog“ chip (IC8) supplies power to t he RAM ICs from the 5V supply rail, but changes over to t he 3V Lithium backup battery when the 5V supply drops below a s et level.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type
recommended by the manufacturer. Dispose of used
batteri es accordin g to the ma nufac turer’s ins truct ions.
3.6.3 DMX input / output
DMX signal is received via switching relays (RLY1, RLY2) that allow the DMX t o be t erminated or looped thro ugh. Whe n terminated, the CPU has the ability t o drive the data output for future readback systems, however in normal operation the incoming data is connected directly to the LOOP output.
The balanced DMX input signals are buffered and unbalanced by a 75176 (IC12) before passing to the serial port of the µP.
3.6.4 Zero crossing detector
The zero crossing detectors synchronise CPU ramp generation to the mains supply. Each phase transformer output is rectified, divided, and compared (IC14) with a reference voltage generated from the +5 volt rail. The three comparator outputs should be low­going pulses roughly centred around t he mains zero-cr ossing point, with a 10 ms cycle t ime.
3.6.5 Analog to digital converter (ADC)
As well as being used to generat e zero-cr ossing pulses, the three transformer secondar y voltages are resistively divided and multiplexed into t he 8 bit A-D co nverter ADC0820 (IC4) via the 4051 analog switch (IC6). This mux is controlled by a latch 74HC574 (IC5 pins 14-19). The temperature sensor and a spare input from the Output PCB are also connected to the mux inputs.
The ADC is read approximately every 2ms in software V1.1F, however this may change with later software versions.
The phase voltages are compared in the µP to obtain “bad neutral” information. The temperature sensor voltage is converted to degrees and can be displayed on the front panel PCB.
3.6.6 Optocoupler drive
The µP directly drives 12 ULN2003 inverter buffers (IC9, IC13) which in turn drive the BR T12 op to co up ler s or po wer os cillat o rs ( o n th e Ou tp ut PC B) to fire the t riac s/S CR s. These signals pass down the Output card flat cable, along with the power supplies.
Equipment Description 3-10
Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
3.6.7 5 volt power supply
All electronic circuits other than the fan controller are run from a 5 volt supply, regulated from the 15 V supply with a LM2576-5 switching regulator (REG1) operating as a continuous-mode buck converter at approx 52kHz..
The demand on the 5 V rail is around 750 mA. A conventional linear regulator would need to dissipate around 7 watts. This loss is reduced to less than 0.5 watts by using a sw itc hing re gu lat o r . . This cir cu it is r elia ble in op er a tio n but it ma y be d ama ge d b y lon g periods of very high mains voltage, eg. over 300Vac.
If not working, check the regulator or flyback diode D1. Note that D1 should only be replaced with a suitable high speed flyback diode designed for use in switchmode power supplies. Also check inductor L1 for mechanical failure.
An MC78L12CG 12 volt regulator (REG2) pro vides a supply rail for programming th e FLASH devices. A two tr ansistor switch (Q2, Q4) controlled by IC5 pin 13 connects this 12 volt ra il to t he FL ASH de vice whe n pr og ra mming is req uir ed . I n ge ner al t his c ircu it should not be active - it is only active during software upgrades to FLASH.
3.6.8 Reset generator
The reset generator is based around a MAX691 (IC8). This IC monitors t he +5 volt rail and pu ts th e CP U int o re set if t he vo lt age is be low 4. 6 vo lt s. The RES ET LE D s hou ld flash briefly when power is applied and removed, and when the RST terminals are shorted together. IC8 also disables the SRAM via the CE pins and switches SRAM power from the main supply to t he backup battery during power up and down. Capacitor C17 maintains the supply to t he SRAMs during changeover - if a dimmer is d r o p p ing it s memory and the battery is OK this capacitor may be faulty.
Th e Lit hiu m bat te ry s hou ld la st ap pr oxima t ely 5 yea rs from the date the battery was made - note that a 4 year life from date of product sale would not be unexpected when deliver y and manufacturing times are allowed for .
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type
recommended by the manufacturer. Dispose of used
batteri es accordin g to the ma nufac turer’s ins truct ions.
3.6.9 Rotary encoder
While the encoder mounts on the CPU card, most of it’s active circuitry is contained on the front panel card. A pair of 220R/10K/10nF RC networks filter the encoder signals on the CPU card before they are routed t o t he front panel card via the flat cable. The value of these parts is quite critical to correct encoder operation.

3.7 Front panel card
(
Figure 3.4
The front panel PCB holds all front panel switches and LEDs, including the LOAD and DRIVE LEDs which are fed by the Output PCB. Additionally, the control electronics for the switches and LEDs and the encoder circuitry are also on the front panel PCB. To minimise flat cable size, the CPU da ta bus and req uired CPU selec t lines are connected to the front panel card to control the latches for the LEDs and buffers for the switches/encoder circuitry. The majority of components on t his card are Surface Mo unt devices.
3.7.1 Switches
The switches are read individually via tri-state 74HC245 buffers (IC4, IC5, IC6). E ach switch when pressed (closed) pulls the buffer input high, ot herwise a 10K resistor (RN1, RN2, RN3) pulls it to ground.
Note that switch faults will most likely be caused through wear in the switches themselves.
3.7.2 LEDs
Due to t he large number of front panel LEDs (including the four 15 segment displays), all except the Phase LEDs and Drive/Load LEDs are driven in a matrix, the seven rows of which are driven by a 74HC574 latch and BCX17 transistors (IC1/Q1-7/R1-R7). T he 16 columns are driven by two 74HC574 latches (IC2-3/R8-23). T he matrix is driven with only one row o n at any time, each row being on for approximately 2ms out of 14ms. A failu r e in t he matr ix c o uld r e su lt in a r o w be ing d e ad (e g . D ig it 1 o r Gr e e n S e le ct LE D s off) or a co lumn be ing d ead (eg . seg ment 4 o f all dig its fa iled) , els e th e fault will be a single LED dead. It is import ant when tracing matrix faults to refer directly to t he circuit diagram.
Note that the bicolour “Select” LEDs are sensitive to excess so ldering temperature and should be replaced with care.
An RC delay networ k C5/R24 holds the display off for a short period during startup t o ens ur e t h e C PU has t ime t o init ialis e t he ma t rix befo r e t he dis pla y be co mes a ct ive . Th is prevents damage to the display LEDs through over current and ensures that the large current required to feed all segments does not occur .
An RC decoupling network C11/R25 minimises the amount o f noise generated by the LED multiplex circuit that is fed into the 5 vo lt r ail.
3.7.3 Encoder
The encoder output consists of two signals 90 degrees out of phase. These signals have already been filtered on the CPU card, and so are then squared by a 40106 Schmitt (IC8:A/:B/:C). The signals are used to control the 4516 up/down co unter (IC9) such that when the encoder is rotated clockwise the counter co unts up,and when the encoder is rotated counterclockwise the counter counts down. Note that any time the encoder is rotated, pulses should appear on pins 10 and 15 of the counter IC9.

4.1.4.5 “P. FLT” - Mains Power Fault
(
Figure 4.1A
Th e HP series dimmers will detect two types of main s supply problems:
• Mains undervoltages
• Neutral-to- ear th overvoltage
In some venues the three phase power supply may be less than ideal, and one or more of the above fault conditions may occur without the wiring being truly “faulty”. For this reason it is possible (BUT NOT RECOMMENDED) to use the P.FLT option to turn off the power fault detect (the show must go on). ALWAYS check first that the problem is not a dropped neutral in either of the three phase connectors, or a missing earth connection.
WARNING
IF THE NEUTRAL DETECT FACILITY IS DISABLED, IT IS PO S S IBLE
THAT UNSAFE MAINS SU PPLY WIRING MAY NOT BE DETECTED.
The HP dimmers will tolerate and even correct for mains supply problems of sufficient magnitude to damage less tolerant equipment connected to the same supply.

5.1 Protection
The HP Series dimmers feature several types of protection. These can be generally classified as:
1. output protection,
2. t h ermal pr otection,
3. overvoltage protection.
5.1.1 Output protection
Each of the output circuits is protected by a 11.5 amp [25 amp] fast-acting magnetic circuit breaker. Thes e break ers are designed to pass t h e r ated cur ren t, but will discon n ect the output circuit for any overload condition (the larger the overload, the quicker the disconnection).
NOTE: T he dimmer outlet sock e ts a re r a ted at 10 [ 2 0] a mp s . Avoid load in g the dimmer outputs beyond the socket capacity.
The breakers protect the dimmer’s output devices from short-circuit loads and faulty wiring loo ms, a nd save on expen sive dimmer repairs. A tr ipped circu it breaker indicates a load fa ult tha t r equ ires immediate atten tion.
Note that the triacs in the HP12-TR will survive output short circuits under most conditions. The more rugged SCR pairs in the HP12-SC / HP6-C will survive o utput shorts under extreme conditions (high operating temperatures, high supply fault current availability, zero cable length from dimmer to short).
5.1.2 Thermal protection
The HP dimmers feature temperature-controlled fan cooling. As the internal temperature of the dimmer increases, the fan speed also increases. The fan begins turning at low speed at 30°C, and reaches maximum speed at internal temperatures above 50°C.
Disassembly 5-2

T he fan will cont in ue to cool t he he atsink during the shut down p eriod.
The electronic shutdown at 85°C is backed up by a 90°C buried cutout, which shuts down power t o all electronics other than the cooling fan.
No te t hat the HP6- C / HP 12-SC's two fans w ill run s lower and qu iet er u nder aver age operating conditions than the HP12-TR's single fan, due to the increased airflow ca p a c ity. In addition the fa n s in wall- moun t dimmer s w ill run s lowe r and quie ter than the fans in rack-mount dimmers d ue to in cre ased natural c onvective c ooling.
5.1.3 Supply Power fault protection
Th e H P s er ies dimme rs will d et e ct vo lt ag e p r ob lems ge ner at e d b y ph as e lo a d imb ala nce and a poor o r missing neutral connection. A poor ( r esistive) neutral connection can cause arcing and overheating of the connecto r, and also allows the phase-to-neut ral voltages to vary, causing overvoltage damage to co mponents.
Bad neutral connections account for many lamp and dimmer fa ilur es. While the int er nal electronics of HP dimmers can tolerate (and correct for) these fault conditions, other equipment run from the same mains supply generally cannot.
Th e HP series dimmers will detect two types of main s supply problems:
• Mains undervoltages
• Higher than normal neutral-earth voltages
In add it io n, t he HP se rie s d immer s c an c o rr ec t an d r eg ula t e t he dimme d o u t pu ts ag ain st variations in the mains supply voltages.
The HP dimmers’ electronic circuits will tolerate gross overvoltages and accidentally transposed act ive-neutral connection with no internal damage and no damage to output loa d s.
5.1.3.1 Mains Undervoltage
If voltage on any phase drops below the minimum (approximately 100 volts AC) for more than 2 cycles
the outp ut s on t hat pha se a re disa bl ed until t he volta ge ris es a bove a p r eset
level
. When th e und ervo ltage c ondit ion is re moved , the dimmer w ill reactivate the low
phase. The outputs will re start according to t he previous settings.
5.1.3.2 Neutral - Earth Voltage
If the voltage between the neutral and earth exceeds the maximum, t he dimmer ou tp ut s are turned OFF and the following message scrolls across the display: “NEUTRAL EARTH FAULT. PRESS NORMAL TO REACTIVATE”. When the neutral-earth vo ltag e con d itio n is removed, p res s the NORM AL butto n to react ivate the dimme r . Th e out puts w ill res tart according to the previous settings.
Neutral-earth voltages are most commonly caused by poor (resistive) neutral connections, undersized neutral wires in supply cables, and missing or disconnected earths. Screw t erminals in connectors can loosen with use and these should be checked when this fault occur s.
Th e neutral det ect fac ility may be d isabled via the MODE menu. Refer to section 4.1.4.5 for deta ils.

Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
5.2 Output faults
If a short-circuit lamp or output cable is plugged into t he dimme r , t he circ u it br e a ker w ill act within milliseconds to disconnect the fault from the dimmer. In nearly all circumstances, this is quick enough to prevent damage to the output devices.
HP12-TR: If a tria c fails, it will either t urn a channel o n to full (t riac shor t-circ uit) , or turn it off
(triac open-circuit). If a triac fault should occur, that channel may be isolated with its circuit breaker.
A loc ked-on ou tpu t will u sually b e cau sed by eith er a fa ulty t riac or o pt o-is olat or. To discover which it is, use a soldering iron to lift one end of the gate feed resistor (RT1 t hru RT1 2) and ap ply po w er t o th e dimme r. If t he cha nnel is st ill on th e t ria c is fau lty, otherwise the opto is faulty.
HP12-SC, HP6-C: If a n S C R fa ils , it w ill g e n e r a lly a ppe a r a s a s h ort, lo cking tha t ch a n ne l to full. I f a n SCR
fails open-circ uit, t he o ther SCR will genera lly con tinue to func tion, and tha t chann el will deliver half-wave rectified waveforms to the load.
If a SCR is discovered to be faulty, replace bot h devices for that channel. NOTE: The channel LOAD LE D may be use d t o aid in tr ou blesh oo ting . T his r ed L ED ser ves
two fu n c tion s . I n norma l o p e ration , it a cts a s a n outpu t mimic. Whe n the c ha n nel dr iv e is at zero , it indicates whether that channel’s load is disconnected (or open-circuit).
See section 2.1, item 11 for more information on load checking procedures.
5.3 Operating faults
If a message should appear scrolling across the display: “ADDRESS EXCEPTION ERROR XXXXXXXX XXXXXXXX XXXXXXXX” where the Xs represent different
characters, write down the characters and contact JANDS Service Department or your local J AN D S Dis trib u to r , giv ing details of th e d immer’ s ope r atin g c ond itio ns tha t ca u s e d the error, and software version (see section 4.1.4.3). In the meantime, doing a Deep Cle ar (see section 4.2 ) should ge t the dimmer workin g ag ain.
5.4 DMX faults
Th e H P Dimmer s fe a ture a “L a s t Hold” fac ility t ha t “r e me mb e rs” the la s t r eceived DMX message. In the event of a DMX signal cable being unplugged or severed, the dimme r s will continue to output the “ Held” DMX lev els u ntil a new DMX message is provided , or a Snapshot, Scene o r Chase function is selected.
The DMX IN LED will light if there is a DMX signal.
Disassembly 5-4
Revision 2 - 26 April, 2000 HP SERIES DIMMER TECHNICAL MANUAL
5.5 Phase fault indication
The three green PHASE L EDs will light when all th ree power input phases are presen t.
WARNING
If one or more PHASE LEDs is off, IMMEDIATELY d i scon n ect power to the
dimmer and check the mains supplies and wiring before re-connecting power to
the d i mme r.
5.6 Cold lamp filaments
Co ld lamp fila me n ts c onsu me con s id e rably mor e p owe r th a n w a rm filame nts. Th is me a n s that the first time the lamp is turned on to full, the surge current can be up to ten times greater than the rated cur r ent for the lamp.
This cold surge current may be enough to trip the output circuit breakers. If this “nu isa nc e - t r ipp in g” o f t he c ir cu it b r ea k er s is a p r o ble m, t h e fila me nt P r e he at fa c ilit y ma y be utilised . See section 4.1.4 .5 for inst ructions on e nabling the Preheat fac ility.
Lamp filament resistance is roughly propo rt ional to temperatur e. A filament preheated to 900°K (630°C) has a resistance about three times higher than a filament at room temperature (300°K, 30°C).
Preheat turns on the selected channels a very small amount (around 1% at 240 volts and 4% at 110 volts) which heats the lamp filaments and increases their electrical resistance. When the lamp is then turned on full, the surge current is much less and the circuit br eak er will not trip .
Other advantages of using Preheat are an increase in lamp life (due to the reduction of thermal shock to the filament s), and a reduct ion of lamp heat up t ime (the lamps will flas h sligh tly quick er).
5.7 Memory failure
Th e lit hiu m ba t t e r y on t he CP U c ar d ha s a limit e d life o f four to five yea r s an d w ill ne e d replacing if the dimmer st arts to show signs o f memory failu re.
If t he dimmer lo ses its memor y, it is impor tan t that a Dee p Clear ( see s ect ion 4.2) be performe d when power is app lied to ensure relia ble operation.

7.0 Test and Configuration Settings
7.1 CPU self-tests
A number of CPU test rout ines are contained in the EPROM. To run t hese tests set DIP switch 3 on, DIP switch 4 off, and set DIP Switches 1 and 2 as required (see below) and apply power.
SW1 OFF, SW2 OFF: CPU RAM test. The green LED should light after
approximately 15 seconds. Note that this test corrupts the CPU RAM therefore
a Deep Clear (see section 4.2) must be performed afterwards when the CPU is to be used in a dimmer.
SW1 ON, SW2 OFF: CPU ADC test. A DAC is plugged into the “MUX
EXPANSION” socket and a crude linearity test is performed on the ADC. T he green LED should light after ap proximately 0.2 secon ds. The DAC is shown on the circuit diagram.
SW1 OFF, SW2 ON: CPU DMX loopback test. A link lead is connected
between the DMX Loop and the DMX Input socket, and data is transmitted and checked for correct reception. The green LED should light after approximately 0.5 seconds. The relays should click at the commencement of this test.
SW1 ON, SW2 ON: Front panel interface test. The front p anel bus is t e st ed
with a known goo d front panel PCB by reading the switches and lighting the assoc iate d LED. ie . the channe l LED will illuminate (bot h colours) when the cha nnel “S elec t” s witc h is pr esse d, t he keyp ad LE Ds w ill illumina te w hen t he associated buttons are pressed. When the “Enter” button is pressed the “Sig nal” LED illuminates. The encoder circuit is also tested here - when the encoder is turned the number in the display should increase or decrease de pending on which way it is turned. This t est can a lso be used to t est fron t panel PCBs.
Test Limitat i o n s:
The zero cro ssing generators are not tested.
The encoder test r elies on the operato r to check proper o peration in both up
and down directions.
The analogue mux input circuit is not adequately tested.
The FLASH program voltage is not test ed.

Th is is a basic in-fie ld fu nct ion al t est , to be p er for med on p ow er car ds follo wing majo r surgery. Unlike full factory tests, an elaborate t est fixture is not required. It is assumed that the dimmers' frontpanel card, CPU card and chassis wiring are present and functional.
The power card must be complete, with the triacs/SCRs, fan and heatsink plates mount e d, a n d the w ir in g to the b r eak e r s , o u tpu ts a n d c h oke s c onne c ted. Y ou w ill n e e d a DVM. Have a circuit diagram handy, to show the pinouts on the 26-way connector .
1. Impo rtan t firs t ste p: Measure t he resistance from A1 to N1, A2 t o N2 and A3 to N3. This should be about 1400 ohms (TR) or 750 ohms (SC). If it is only about two hundr ed ohms, a tra nsformer is mounted backwards or is sho rt circ uit ..

T he lamp limits the ene rg y if a fau lt t o gr ou nd or a short is present. Operate the "death lead" only from an RCD- or ELCB­protected outlet.
At turn-on, a 100W series lamp should barely glow. A bright light indicates a
short to neutral. A tripped RCD/ELCB indicates a short to earth.
Check tha t the display is not sho wing error or wa rning messages
Check the DC supply voltage from TP- to T P+ ( about 16Vdc).
Check the temp-sense voltage from TP- to TPT ( 200- 300mV).
Check for 5V supply from TP- to T P5.
Turn on the frontpanel breakers one at a time; check that the LOAD indicator
for each channel functions and that t he lamp glow do es not change.
Heat the temperature sensor with a soldering iron and check that the fan speed
changes with temperatur e.
Connect a (different) load lamp to each o utput and check that the LOAD LED
goes out, and that the test lamp does not light (ie. the load-sense and triac/SCRs work).
Bypass the 100W protection lamp, and apply full mains. Use the TEST
function to drive a 100W lamp from each channel in turn. Check that the LOAD and DRIVE LEDs operate correctly, and that the load lamp can be controlled from zero to full intensity.
7.3 Phase Compensation
DIP switches 1 and 2 on the CPU card are used to specify the amount of phase compe n sation for different generations of Ja nds HP dimmers as follow s:
Product Switch #2 Switch #1
HPTR/SC dimmer unmodified O ff Off HPTR/SC dimmer modified per te ch note TB JLT068 Off On Original HP dimmer unmodified Off On Original HP dimmer modified p er tech no te TBJ LT0 68 On Off
