2.4 Connect Back-Up Power
The monitoring system and chart recorder each have a back-up battery system enabling a period of continuous operation if power
is lost.
Battery life varies by manufacturer, voltage level remaining as well as whether optional Access Control is installed. Providing full
power is available, Access Control is not installed and no battery-related alarms are active, back-up power for the monitoring
system is available for up to 20 hours (the Low Battery alarm will activate after approximately 18 hours of battery use). Providing
full power is available, back-up power for the monitoring system and optional Access Control system is available for up to
2.5 hours.
CAUTION
Before installing or replacing batteries, switch AC power and back-up battery switches OFF. Disconnect refrigerator from
AC power.
Notes
• The optional Access Control system uses the monitoring system back-up battery for back-up power in the event of
power failure.
• The monitoring system will start on back-up battery power alone. If the refrigerator was not previously connected to AC
power and the back-up battery is switched on, the monitoring system will begin running on back-up battery power.
• If AC power is lost, the monitoring system will automatically disable some features to prolong back-up battery power.
Data collection will continue until back-up battery power is depleted.
The back-up battery is located below the chamber, behind the right side panel. The panel cover must be removed to access
the battery.
Monitoring system back-up battery.
2.5 Prepare for Monitoring
The back-up battery switch is switched OFF for shipping. Switch the back-up battery switch ON to provide the monitoring system
and optional Access Control system with back-up power in the event of AC power failure.
Temperature Probes
Notes
• Temperature probes are fragile; handle with care.
• Remote probes may also be introduced through the existing port and immersed in existing probe bottles.
• External probes should not be routed into the chamber through the door opening as this may cause issues with the
door seal.
• Solid ballast (if installed) should be placed in the bracket in a horizontal position.
A solid ballast or probe bottle and container of glycerin have been provided with this unit. When using the probe bottle, mix the
glycerin with water to create a solution which simulates the product stored in the refrigerator. The product simulation solution
temperaturereectstheproduct’stemperatureduringnormaloperation.
The probe bottle should contain 4 oz. (120 mL) of product simulation solution at a 10:1 ratio of water to glycerin.

2. Insert probe through port into chamber.
3. Insert probe into bottle or secure in ballast with thumbscrew.
4. Replace putty, ensuring a tight seal.
Chart Recorder (if included)
Note
• If chart recorder has been operating on battery power, the battery should be replaced to ensure the back-up source has
proper charge.
• For complete information, refer to the Temperature Chart Recorder Operation and Service Manual.
The chart recorder has a back-up 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, back-up power for the temperature chart recorder
is available for up to 14 hours.
Prior to use:
Route the chart recorder probe through the rear access port and place in bottle with primary monitor probe, or install in ballast and
secure with thumb screw.
Set up and Operation
Access chart recorder by pulling the door to open.
Install Battery
Connect the leads to the battery to provide back-up power to the chart recorder.

Install / Replace Chart Paper
Notes
• For accurate temperature reading, ensure the current time is aligned with the time line groove when chart knob is
fully tightened.
• Contact Helmer Customer Service or your distributor to reorder chart paper; part number 220366 (52 sheets).
Chart recorder stylus and time line groove
1. Press and hold Cbutton.Whenstylusbeginstomoveleft,releasebutton.TheLEDashes.
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 in place while making sure the chart knob is fully tightened. (Failure to fully tighten the knob can result in paper
slipping and losing time.)
6. Press and hold C button. When stylus begins to move right, release button.
7. Conrmstylusismarkingonpaperandstopsatthecorrecttemperature.
8. Calibrate chart recorder to match primary temperature if needed and close recorder door.
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33V(RMS)or70V(DC)isconnectedtotheremotealarmmonitoringsystem’scircuit,
the remote alarm will not function properly and may cause damage to the control board or result in injury to the user.
The terminals on the remote alarm interface have the following maximum load capacity:
♦115V or 230V: 1 A at 33 V (AC) RMS or 70 V (DC)
Connect to Remote Alarm Interface
1. On the electrical box, locate the remote alarm terminals.
2. Connect remote alarm wires to appropriate terminals, according to requirements for your alarm system.
3. Use a cable tie to relieve strain on alarm wires (as necessary).
