1.5 Chart Recorder
If installed, refer to the Temperature Chart Recorder Operation and Service Manual.
The chart recorder has a battery system, enabling a period of continuous operation if power is lost. Battery life varies by
manufacturer as well as voltage level remaining. Providing full power is available, backup power for the temperature chart recorder
is available for up to 14 hours.
Prior to use:
♦Install battery.
♦Add paper.
♦Calibrate chart recorder to match upper chamber temperature.
Open door by pressing and releasing.
Install Chart Paper
Note
For accurate temperature reading, ensure that current time is aligned with time line groove when chart knob is tightened.
1. Press and hold C button. When stylus begins to move left, release button. The LED ashes to indicate current
temperature range.
2. When stylus stops moving, remove chart knob then move knob up and away.
3. Place chart paper on chart recorder.
4. Gently lift stylus and rotate paper so current time line corresponds to time line groove.
5. Hold chart paper and reinstall chart knob.
6. Conrm temperature range is set to the correct value.
7. Press and hold C button. When stylus begins to move right, release button.
8. Conrm stylus is marking temperature correctly.

2 InstallationandConguration
2.1 Install Batteries for Backup Power
The monitoring system and chart recorder each have a battery system, enabling a period of continuous operation if power is lost.
Battery life varies by manufacturer as well as voltage level remaining. Providing full power is available and no battery-related
alarms are active, backup power for the monitoring system is available for up to two hours.
The batteries are located on the top of the platelet incubator, under a removable access panel.
Batteries are disconnected for shipping. Reconnect batteries to provide monitoring system with backup 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 toAC
power and the batteries are connected, the monitoring system will begin running on battery power.
• IfAC power is lost, the monitoring system will continue to collect data until battery power is depleted.
CAUTION
Before installing or replacing batteries, switch the power OFF and disable backup power to the i.Center monitoring system
by switching the ON/OFF key switch OFF (located behind the control door). Disconnect the platelet incubator from AC
power.
NOTICE
Use only manufacturer supplied battery when installing a replacement battery.
2.2 PlateletAgitatorandPlateletIncubatorCompatibility
i.Series platelet incubators may be tted with i.Series platelet agitators. When installed in an i.Series platelet incubator, the i.Series
platelet agitator can be monitored by the platelet incubator’sAgiTrak™ 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 i.Series platelet incubators can monitor i.Series platelet agitators.

2.3 InstallaPlateletAgitatorinthePlateletIncubator
Notes
• This section is not applicable to the PC4200i platelet incubator, which has a built-in platelet agitator.
• For additional instruction on conguring a platelet agitator in a platelet incubator, refer to the platelet agitator service manual.
PC900i platelet incubator with a PF48i platelet agitator installed.
Helmer platelet agitators can be installed inside Helmer platelet incubators. i.Series platelet agitators can be connected to i.Series
platelet incubators via a data cable. The connection allows the platelet incubator to monitor the platelet agitator motion, and to
sound an alarm when agitation motion stops.
PC2200i and PC3200i platelet incubators hold 1 agitator per shelf. Each shelf features a corresponding power connector. In
PC2200i and PC3200i platelet incubators, each shelf includes a data port. Through the data port and data cable, agitation motion
is communicated from i.Series platelet agitators to the i.Series platelet incubator.
When installing a platelet agitator on a shelf, use the power connector for that shelf to prevent the power cord from obstructing the
agitation motion. When installing an i.Series platelet agitator on a shelf in an i.Series platelet incubator, use the data port for that
shelf so agitation motion is communicated appropriately.
2.4 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.
CAUTION
• 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 30 V (RMS) or 60 V (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.
NOTICE
• For any platelet incubator (except PC4200i) without a platelet agitator installed, a bypass plug is needed for a normally-
closed interface circuit.
• The bypass plug is needed if multiple platelet agitators are installed, and not all are Helmer i.Series platelet agitators.
For each position in which a non-Helmer i.Series platelet agitator is installed, the bypass plug must be installed in the
data port.
• To obtain a bypass plug, contact Helmer Technical Service.
The terminals on the remote alarm interface have the following maximum load capacity:
♦0.5 A at 30 V (RMS)
♦1.0 A at 24 V (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.
2.5 CongureDrawers(PC4200i)

3.4 Calibrate Temperature Probes
Verify the temperature probe(s) are reading chamber temperature correctly by comparing the chamber probe reading to
temperature read by an independent thermometer. If the chamber temperature probe(s) are not reading correctly, change the value
displayed on the temperature monitoring system.
Notes
• If the variance is within acceptable limits for your organization, changing probe settings is optional.
• Default setting for chamber temperature is 22.0 ºC. Value is factory-preset
• Value can be changed from -40.0 ºC to +40.0 ºC
CalibrateProbe(s)
Model Location Model Location
PC100i Front, top right corner PC3200i Upper reading: next to upper temperature probe
Lower reading: next to lower temperature probe
PC900i, PC1200i Back, right bottom corner PC4200i Upper or lower reading: in the middle shelf on the right side
PC2200i Next to upper temperature probe
1. Using the table above, place a calibrated independent reference thermometer traceable per national standards in the
specied location.
2. Close the door and allow the chamber temperature to stabilize for 30 minutes.
3. Observe and note the thermometer temperature.
4. On the Home screen, press the MAIN button.
5. Press the DOWN button to highlight Edit Conguration. Press the SELECT button.
6. Enter the password when prompted.
7. Press the DOWN button to highlight Temperature Calibration. Press the SELECT button.
8. Follow the system prompts for Model Type.
♦For models with two probes, press the UP or DOWN buttons to select the Upper Probe or Lower Probe options. Press
the SELECT button, then press the DOWN button to highlight the Temperature option.
♦For models with one probe, the Upper Probe option is displayed and the Temperature option is highlighted.
9. Press the INC or DEC buttons to change the displayed value to match the value measured by the
independent thermometer.
10.Press the DOWN button to highlight Store Calibration.
11. To save the new value, press the ENTER button. The “Calibration Memorized” message appears. New settings are saved.
12.To discard the new value, press the BACK button to return to the Edit Conguration screen, or press the HOME button to
exit. New settings are not saved.
13.Remove the thermometer from the chamber and close the door.
Notes
• The current temperature displayed by the monitoring system may change so that it no longer matches the new probe
calibration value. This is normal.
• If a new probe value is entered but not saved, the new value will appear when the calibration setting for the probe is
viewed. This is normal.
