HEALTH SAFETY TIMER
STARTUP
A UPS battery backup is included so temperatures can still be monitored and the lock can be actuated during a power outage.
The UPS is powered "off" when shipped from True and will need to be powered "on" upon start-up (see instructions on page 9).
The cabinet's Health Safety Timer feature will not be fully operation for 8 hours. This time is required for the UPS battery back up system to
fully charge.
The UPS will provide power to the controller for a minimum of 2 hours.
When power is lost to the cabinet the UPS will beep and the control will display
"Pf"
.
Note: The cabinet will lose its cooling capabilities when the power is lost.
When initial power is supplied to the cabinet, the control will indicate a delay.
The displayed on the control will alternate between
"hSt"
and
"dLy"
.
This delay allows the cabinet to reach temperature without a false alarm. 60 minutes for a refrigerator and 105 minutes for a freezer.
If additional time or a delay event is needed, follow the directions titled "Enabling the Product Loading Delay and Servicing Delay".
OPERATION
The Health Safety Timer cabinet's operation is determined by the electronic control.
The electronic control constantly monitors the cabinet temperature.
The control will activate a locking device when preset parameters of temperature (41˚F - Refrigerator / 0˚F - Freezer) are exceeded for a
duration of 30 minutes.
These parameters are pre-programmed.
When the temperature alarm is triggered, the door will mechanically lock and the control will a provide a visual and an audible alarm. The
displayed on the control will alternate between
"Loc"
and
"hLa".
The alarm can be cleared by following the directions titled "Clearing the Health Safety Timer Alarm".
A key is required to reset the mechanical locking device and open the door once the Health Safety Timer has been activated.
Note: It is recommended to clear the alarm on the control first, otherwise door will relock when is closed again.
Note: In case of an emergency, the door may be opened from the inside with a pull cord (see instructions on
page 11).
If the door remains open for 5 minutes, as determined by the door switch, the control will provide a visual and an audible alarm. The
displayed on the control will show
"do"
.
Any audible alarm can be silenced by pressing the center "Enter/Confirm" button twice.
Note: Alarm will still be displayed on control until its condition has been corrected.
