Service Manual


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 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.

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 fitted 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’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 i.Series platelet incubators can monitor i.Series platelet agitators.

2.3 Install a Platelet Agitator in the Platelet Incubator

Service Manual

Notes

• This section is not applicable to the PC4200i platelet incubator, which has a built-in platelet agitator.

•

For additional instruction on configuring 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)

360096-1/P

Motion Alarm (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 the Agitator 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 the Agitator 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 flat-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.

Change Motion Alarm Delay:

Using a small, flat-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.

Change Motion Alarm Volume:

1. On back of the platelet incubator, locate the alarm volume control.

2. Position the switch to correspond with the desired motion alarm volume.

Note

The PC4200i’s built-in agitator transmits motion and speed information directly to the AgiTrak system without a separate data cable.

The platelet incubator has a data port for each platelet agitator position. The installed platelet agitator transmits motion and speed information to the AgiTrak system through a data cable and the data port in the platelet incubator. The AgiTrak system monitors platelet agitator motion on/off status and current agitation speed.

If motion is not detected for the pre-configured amount of time, the AgiTrak system activates an alarm and records the alarm event(s) in the event log. For agitation information to be monitored correctly, each platelet agitator position must be enabled in the

AgiTrak interface.

Disable a platelet agitator position through the AgiTrak interface under the following conditions:

♦

The position is not available

♦

The position is not in use

♦

The position has a Horizon Series agitator installed

Note

If a Horizon Series platelet agitator is installed in the platelet incubator, its position (in the AgiTrak interface) should be disabled to prevent false alarms.

The Agitator Alarm Setpoint specifies the longest the agitator can be stopped prior to alarm. If the time elapsed is greater than or equal to this value, an alarm activates. The default setting is three minutes. The Setting can be changed from 0 minutes to 60 minutes

Note

The AgiTrak system is intended to replace each i.Series platelet agitator alarm. The motion alarm on each installed i.Series platelet agitator should be disabled when using the alarms in the AgiTrak system.

4.5 Platelet Incubator Setpoint

The default setpoint is 22.0 °C. The temperature controller adjusts chamber temperature around the setpoint. When chamber temperature is below setpoint, the controller activates the heater to warm the chamber. When temperature rises above setpoint, the controller deactivates the heater to allow the chamber to cool. The compressor runs continuously.

NOTICE

Do not change the setpoint to a value outside the temperature control range.

Open the control door to access the temperature controller. The current chamber temperature is displayed. The temperature may be different from the setpoint, especially if the chamber temperature has not yet stabilized.

4.6 Calibrate the Temperature Controller Display

The temperature controller senses chamber temperature through a probe in the chamber. The chamber setpoint typically varies from the measured temperature, so an offset value is used by the control system to compensate for the difference.

NOTICE

Do not change the control sensor offset unless instructed in product documentation or by Helmer Technical Service.

Notes

• Value is factory-preset and varies for each unit

• Offset value can be changed from -10.0 °C to +10.0 °C

• If the variance is within acceptable limits for your organization, changing the offset value is optional.

Determine New Offset Value:

1. Use the zip tie to attach a calibrated independent thermometer traceable per national standards to the control probe.

2. Close door and allow chamber temperature to stabilize for 30 minutes.

3. Observe independent thermometer temperature for 10 minutes and determine temperature range.

4. From the range, calculate the average temperature.

5. Remove the thermometer from the control probe.

6. Determine the change in value to reach desired setpoint.

Example ♦ Current setpoint is 22.0 ºC

♦

Average temperature is 23 ºC

♦ Offset adjustment value is +1.0 ºC

Horizon Series™ Models


10.1 Install Battery for Backup Power

The monitoring and control system and the 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. The power failure backup battery provides power to the power failure alarm in the event of an AC power failure. Backup battery power for the chart recorder is available for up to 14 hours.

CAUTION

Before installing or replacing the battery, switch the power OFF . Disconnect the platelet incubator from AC power.

NOTICE

Use battery meeting manufacturer’s specifications.

The battery is located behind the control door.

Battery is disconnected for shipping. Reconnect the battery to provide power failure alarm with backup power in the event of AC power failure.

10.2 Platelet Agitator and Platelet Incubator Compatibility i.Series countertop platelet agitators (PF15i, PF48i, and PF96i) have a built-in motion alarm system and may be placed in either i.Series or Horizon Series platelet incubators. When agitation motion is not detected, the alarm sounds.

An i.Series platelet agitator placed in a Horizon Series platelet incubator cannot be monitored by the platelet incubator. If the agitation motion stops, the alarm on the i.Series platelet agitator sounds inside the platelet incubator, so the sound may not be apparent. An extension to the alarm system is desirable for this configuration.

Note

Horizon Series platelet incubators cannot monitor i.Series platelet agitators.

10.3 Install a Platelet Agitator in the Platelet Incubator

Note

This chapter is not applicable to the PC4200h platelet incubator, which has a built-in platelet agitator.

Service Manual

PC900h platelet incubator with a PF48h platelet agitator installed.

Helmer platelet agitators can be installed inside Helmer platelet incubators. PC2200h and PC3200h platelet incubators hold one agitator per shelf. Each shelf features a corresponding power connector.

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.

Horizon Series platelet agitators (PF15h, PF48h, and PF96h) are not equipped with motion alarms, but may be placed in any

Series platelet incubator. Without motion alarms, Horizon Series platelet agitator motion cannot be detected by the AgiTrak system in i.Series platelet incubators.

Note

For additional instruction in configuring a platelet agitator in a platelet incubator, refer to the platelet agitator service manual.

10.4 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.

The terminals on the remote alarm interface have the following maximum load capacity:

♦

0.25 A at 30 V (RMS)

♦

0.25 A at 60 V (DC)
