Pack recovery can be used in the event of a pack failure. When the selected input is activated, all the case controllers operating from the
pack (set up in Case Setup page) can either be placed into ‘Case Off’ or have their refrigeration valves forced closed. When the input
has cleared, the DMTouch will begin a recovery process and allow a pre-determined number of controllers to begin opening their valves
over a set period of time. Mercury case controllers must have the appropriate software to use this feature. The software must have the
Remote Command “EEV Command” present before this feature will work. Consult appropriate case controller user document to
determine software version required.
Pack Fail Ctlr - Select the source of the pack failure from a controller in the device list.
Pack Fail Input - Select the source of the pack failure input from the controller selected above.
Use Standby - If the Pack Fail Ctlr selected is a pack controller then ticking the Use Standby option will force controller
valves closed whenever the pack controller is in standby instead of using a dedicated input.
Recovery Count - The number of controllers allowed to open their valves, once the recovery process starts, in a given
period. Each period is fixed at one minute. If this parameter is set to 3 then 3 case controllers would begin
refrigeration once the pack fail input has cleared, after a one minute delay a further 3 controllers will start
the refrigeration process until all cases resume normal refrigeration control.
Fail Type - This field dictates what command is sent to the controller. ‘EEV Close’ will send a command to close the
valve of the controller. ‘Case Off’ will send the command to put the unit in the ‘Case off State’.
Note: When input equals “1” then pack ok and when input equals “0” then pack fail.
Optimisation Setup
On the Optimisation Setup section enter the following;
Period (mins) Enter the period over which optimisation is based
Opt Up Value - Enter the % efficiency below which will optimise up
Opt Down Value - Enter the % efficiency above which will optimise down
Opt Zero Value - Enter the % efficiency for no optimisation
Single Case Zero Count - Enter the number of Periods a single case reaches the “Opt Zero Value” before optimisation is turned off
Multiple Case Zero Count - Enter the number of cases that reach the “Opt Zero Value” during a single period before optimisation is
turned off
Defrost Valve Setup
On the Defrost Valve Set up section enter the following
Valve Device - Select the appropriate defrost header station controller from the drop down list.
Valve output - Determines the relay that will be operated. Valve open command sent to the selected controller relay when any case on
the network is in defrost.
Case Running (%) - Enter number of cases which have to be online before optimisation is enabled.
Pack recovery can be used in the event of a pack failure. When the selected input is activated all the case controller refrigeration valves,
operating from that pack as selected in Case Setup, are forced closed. When the failure has cleared the DMTouch will begin a recovery
process and allow a pre-determined number of devices to begin opening their valves over a set period of time. Note Mercury case
controllers must have the appropriate software to use this feature, see Mercury user document for further details.
