  • Page 4: Important Safeguards

    Throughout the MaxPac User Manual, the safety alert and the international electric shock/electrocution sym- bols will alert you to potential hazards. Safety precautions should always be followed to reduce the risk of personal injury to persons from fire and electrical shock hazards. Safety Alert Symbol International Shock/Electrocution Symbol Each safety message is preceded by a safety alert symbol and one of three words: DANGER, WARN- ING, or CAUTION. These mean: DANGER You WILL be killed or seriously hurt if you do not follow instructions. WARNING You CAN be killed or seriously hurt if you do not follow instructions. CAUTION You CAN be hurt if you do not follow instructions. Damage Prevention Messages: CAUTION You will see other IMPORTANT messages that are proceeded by the word that are intended to help prevent damage to the MaxPac™ or other equipment. Note that Damage Prevention Messages are NOT accompanied by the Safety Alert Symbol. 1-888-996-9258 © 2014 Chromalox , Inc. - 3 - ®...

  • Page 5: Description

    MaxPac IP The Chromalox MaxPac IP utilizes Single Phase, Phase Angle firing to modulate power to an inductive or resistive load. Phase Angle control has the advantage of proportioning every cycle thereby providing very fine resolution of power. Fast responding loads in which the resistance changes as a function of temperature require Phase Angle control. The MaxPac IP offers a Soft Start feature that assures that the load power is gradually increased from zero to the value set by the command signal in the event of a power interruption. In addition, optional Current Limit is used to protect the load, SCR controller and the total system from large surge currents that could occur at start-up. † This can be set to three cycles ‘On’ / three cycles ‘Off’ (see section on installation options). - 4 - © 2014 Chromalox , Inc. 1-888-996-9258 ®...

  • Page 20 CAUTION IMPORTANT: This shutdown overrides the control input only. It will NOT protect against faulted or damaged SCRs. Shorted SCR Detection (optional) This option provides a means of alerting an operator to a problem with the system. An external indicating lamp or relay can be connected to J1 - 5 & 6 (see Fig. 2 on page 21). This indicator must be rated for the instrument power applied to J1 - 1 & 2. Three diagnostic LEDs show which SCR pair is faulted. These lights are synchronized with the demand indicator and can only indicate while the demand is active. Shorting J3 - 5 & 6 can disable the output at J1 - 5 & 6. The alarm can be selected as latching or non-latching. A latching alarm means that if the alarm activates and the system subsequently returns to normal, the alarm will remain latched until a reset button (external switch – customer provided) is pressed. A non-latching alarm resets automatically. DEMAND SHORTED SCR DETECTION 1-888-996-9258 © 2014 Chromalox , Inc. - 19 - ®...

This will provide an indication to the operator that the heat sink is approaching an unsafe temperature level. The unit will enter a shutdown mode if the temperature continues to rise. - 20 - © 2014 Chromalox , Inc. 1-888-996-9258 ®...
