Location Requirements
Service Manual
Note Hot ambient temperatures with high humidity may cause condensation on the outside of the unit. ♦ Has a sturdy, level surface. ♦ Has a grounded outlet meeting national electric code (NEC) and local electrical requirements. ♦ Is clear of direct sunlight, high temperature sources, and heating and air conditioning vents. ♦ Meets specified limits for ambient temperature and relative humidity as stated in the Product Specification section of the Platelet Storage Instructions for Use and Operation manual. ♦ Minimum 24” (610 mm) above for ambient temperatures of 28 °C to 35 °C. ♦ Minimum 4” (102 mm) above for ambient temperatures of 15 °C to 28 °C. ♦ Minimum 12” (305 mm) behind for ambient temperatures of 28 °C to 35 °C. ♦ Minimum 4” (102 mm) behind for ambient temperatures of 15 °C to 28 °C.
2.2
Placement and Leveling Note Rear stand-off brackets are provided with the unit and should be installed prior to placing the incubator in its location. 1. Align keyhole openings in stand-off bracket with screws on back of incubator and slide down to engage. 2. Tighten screws using a #2 Phillips screwdriver to secure. 3. Place platelet incubator on sturdy surface. 4. Ensure platelet incubator is level.
2.3
Rear Stand-off Bracket
Connect Back-Up Power
The monitoring and alarm system, and chart recorder each have a back-up battery, enabling a period of continuous operation if power is lost. The PC100-Pro has an optional additional full system back-up battery enabling a period of continuous operation of the incubator and agitator if power is lost. Battery life varies by manufacturer as well as voltage level remaining. The battery must have 48 consecutive hours of power to be fully charged. Providing full power is available and no battery-related alarms are active, back-up power for the monitoring system is available for up to 18 hours. The batteries are located on the top of the platelet incubator, under a removable access panel. The back-up battery switch is OFF for shipping. Turn the back-up battery switch ON to provide the monitoring system with back-up power in the event of AC power failure. Notes • The monitoring system will start on battery power alone. If the platelet incubator was previously not connected to AC power and the batteries are connected, the monitoring system will begin running on battery power. • If AC power is lost, the monitoring system will continue to collect data until battery power is depleted. • Use only a 12V 7AHr SLA battery for the standard monitoring and alarm system battery back-up. • Use only a 12V 18AHr SLA battery (quantity 2) for the PC100-Pro integrated full system battery back-up.
Before installing or replacing batteries, switch the main power switch to OFF and the back-up battery switch to OFF. Disconnect the power cord from the power receptacle.

Platelet Agitator and Platelet Incubator Compatibility
Pro Series platelet incubators may only be fitted with Pro Series platelet agitators. When installed in a Pro Series platelet incubator, the Pro Series platelet agitator can be monitored by the platelet incubator’s AgiTrak™ system. The AgiTrak™ system receives alarm information through a direct connection from the platelet agitator’s alarm system to the platelet incubator’s alarm system. Note Only Pro Series platelet incubators can monitor Pro Series platelet agitators. Platelet Incubator

Install Pro Series Platelet Agitator (Optional)
Helmer Pro Series platelet agitators can be installed inside Helmer Pro Series platelet incubators. The agitator can be connected to the incubator through a data cable. The connection allows the platelet incubator to monitor the platelet agitator motion, and to sound an alarm when agitation motion stops. Power is supplied to the agitator through the coiled DC power cable. Connect the data cable and DC power cable supplied with the incubator prior to placing the agitator inside the incubator. The agitator communication switch must be set to position 1 for use in the incubator. The power cable has a rotating locking feature on each end to ensure a secure connection. When installing the agitator inside the incubator, finger tighten each rotating lock. For additional information, refer to the Platelet Agitator Manuals. Notes • Only Helmer Pro series platelet agitator may be used with Pro series platelet incubator. • Use only the manufacturer supplied power cord when installing the Pro series agitator in a Pro series Incubator. • Retain the agitator AC/DC power supply if shipped with the agitator for potential use in stand-alone configuration. • Ensure the AC power and back-up battery power switches are turned off on the incubator prior to connecting an agitator. • Ensure data cable is carefully positioned to the right of the agitator to prevent damage caused by agitation motion. • The communication switch is fragile, do not use excessive force when changing the setting. • To ensure continuous operation of linearly shifting loads, the location surface must adequately accommodate the full weight of the incubator with installed agitator when loaded with product. • Incubator restraining brackets are included in packaging and recommended when configured with an agitator operating at a setpoint speed greater than 75 cycles per minute (CPM), or when located on a slick surface.

Temperature Probes Notes • Temperature probes are fragile; handle with care. • Remote probes may also be introduced through the rear port.
The temperature monitor and control probes are located on the right side of the unit. NOTICE • The incubator power switch and battery back-up switch must be turned OFF and the AC power cord disconnected from the power receptacle prior to installing an external probe. • DO NOT attach remote probe wires to the AC Terminal block wires or the AC power supply. AC Power Supply
Remote probe routing path Mounting clip
Install Remote Probe 1. Switch the AC power switch to OFF; switch the back-up battery switch to OFF; disconnect the power cord from the power receptacle. 2. Open incubator door and locate the access port plug at the top of the chamber. Use a flat blade screwdriver to pry off the access port plug. 3. Use a #2 Phillips screwdriver to remove the screws securing the top cover, and set top cover and screws aside. 4. Locate the access port on the top of the unit, and peel back the putty. 5. Install the remote probe through the rear panel of the incubator, down through the hole in the top of the unit, and into the chamber. 6. Attach the remote probe to the plastic mounting clip inside the chamber. 7. Secure the remote probe wires to the wire bundle in the top of the unit using wire ties. 8. Reseal the top access port with putty. 9. Reinstall the top cover and secure with screws using a #2 Phillips screwdriver. 10. Reconnect the power cord to the wall receptacle. Switch the main power switch to ON; switch the back-up battery switch to ON. 11. Allow the temperature to stabilize at the setpoint before moving inventory back into the incubator.

External Monitoring Devices
The remote alarm interface is a relay switch with three terminals: ♦ Common (COM) ♦ Normally Open (NO) ♦ Normally Closed (NC) Terminals are dry contacts and do not supply voltage. Interface circuit is either normally open or normally closed, depending on terminals used. Requirements for your alarm system determine which alarm wires must connect to terminals. NOTICE • The interface on the remote alarm monitoring system is intended for connection to the end user’s central alarm system(s) that uses normally-open or normally-closed dry contacts. • If an external power supply exceeding 33V (AC) RMS or 30V (DC) is connected to the remote alarm monitoring system’s circuit, the remote alarm will not function properly; may be damaged; or may result in injury to the user. • For any platelet incubator without a platelet agitator installed, a bypass plug (PN 402149-1) is needed for a normallyclosed interface circuit. The terminals on the remote alarm interface have the following maximum load capacity: ♦ 1A at 33V (AC) RMS or 30V (DC) Connect to Remote Alarm Interface 1. Switch the Battery ON/OFF key switch OFF. Switch the AC ON/OFF switch OFF. 2. On the alarm panel, locate the remote alarm terminals. 3. Connect remote alarm wires to appropriate terminals, according to requirements for your alarm system. 4. Use a cable tie to relieve strain on alarm wires (as necessary). 5. Switch the Battery ON/OFF switch ON. Switch the AC ON/OFF switch ON. 6. Touch MUTE to disable the high temperature alarm while platelet incubator reaches operating temperature.
