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. Conrm temperature range is set to the correct value.
7. Press and hold C button. When stylus begins to move right, release button.
8. Conrm stylus is marking temperature correctly.

2 InstallationandConguration
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 PlateletAgitatorandPlateletIncubatorCompatibility
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 InstallaPlateletAgitatorinthePlateletIncubator
Notes
• This section is not applicable to the PC4200i platelet incubator, which has a built-in platelet agitator.
• For additional instruction on conguring 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 ExternalMonitoringDevices
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)

MotionAlarm(PC4200i)
Unlike other i.Series models, the PC4200i platelet incubator has a motion alarm delay control. When the platelet agitator motion
stops, this control delays when alarm information is sent to the remote alarm interface on the platelet incubator. The alarm delay
control does not delay motion information sent to the AgiTrak system. When theAgitator Alarm Setpoint is reached, the AgiTrak
system activates an alarm, which is also sent to the remote alarm interface on the platelet incubator.
Notes
• To prevent a motion alarm being communicated by an external monitoring device but not by the platelet incubator, set
the alarm delay control to a value greater than theAgitator 1 Setpoint.
• The alarm delay control for the motion alarm is located on the rear of the platelet incubator.
Top: Motion alarm volume control. Bottom: Alarm delay control for the motion alarm.
The default motion alarm delay is set at the halfway point (approximately four (4) minutes). To change the motion alarm delay, use
a small at-head screwdriver. The maximum alarm delay is eight (8) minutes.
The default alarm volume is set at the middle position (medium).
Note
Do not set the alarm delay to 0 minutes.
ChangeMotionAlarmDelay:
Using a small, at-head screwdriver, rotate the control to the left (counterclockwise) to shorten the motion alarm delay, or to
the right (clockwise) to extend the motion alarm delay.
ChangeMotionAlarmVolume:
1. On back of the platelet incubator, locate the alarm volume control.
2. Position the switch to correspond with the desired motion alarm volume.
