ProCuity is the culmination of years of research and feedback from nurses and other healthcare professionals, according to Jessica Mathieson, VP/GM of acute care at Stryker.

“With rising acuity rates leading to increased bed demand, coupled with the continuing challenge of in-hospital falls, we needed to find a solution to further enhance our response to some of today’s most pressing healthcare challenges,” Mathieson said in a news release. ” It was designed to improve patient outcomes and assist caregivers for years to come.”

WARNING! Electrical shock or burn hazard. Powering off an electronic control does not remove power from all components.Unplug the unit or turn off the power supply before proceeding.

Indicator light locations.In addition to reading the control indicator light codes [see “Control Indicator Light Codes0Table” (pg. 13)], note the potential solutions below:Check the terminal connections:If the power wires (Live In and Comp) are reversed, the control indicator lights will not light and the compressor will not start. See fig. 1. for light locations.If the probe wires are reversed, the control will not cycle correctly.Check if the black probe is touching metal. If so, the probe is reading surface temperature instead of return air temperature.Table 1.

ProCuity was designed to help reduce in-hospital patient falls at all acuity levels, improve nurse workflow and safety, and help lower hospital costs, according to Kalamazoo, Mich.-based Stryker. It is the only bed on the market today that can connect seamlessly to nurse call systems without the use of cables or wires, the company added.

Indicator light locations.In addition to reading the control indicator light codes [see “Control Indicator Light Codes0Table” (pg. 13)], note the potential solutions below:Check the terminal connections:If the power wires (Live In and Comp) are reversed, the control indicator lights will not light and the compressor will not start. See fig. 1. for light locations.If the probe wires are reversed, the control will not cycle correctly.Check if the black probe is touching metal. If so, the probe is reading surface temperature instead of return air temperature.Table 1.

Hazardous Food Warning Label (Wine/Chocolate Kit Only)If adjusting the set point to 41°F (5°C) or greater, place the provided hazardous food warning label below the serial label inside the cabinet as shown in fig. 1. This label notifies users the cabinet has been set to maintain a temperature above outside NSF perishable food storage guidelines. Fig. 2. Hazardous food warning label intended location.Before You Begin (Mechanical Controls)If converting a mechanical control to an electronic control, see the following information. If replacing an electronic control, procede to “Temperature Control Installation” (pg. 6).Determine Airflow DirectionDetermine the airflow direction through the evaporator coil. See figs. 1 and 2. Airflow direction dictates probe placement. the black (thermostat) probe will be placed in the return air stream.Fig. 1. The fan motor pushes air through the coil. Place probe on indicated side. Items not to scale.Fig. 2. The fan motor pulls air through the coil. Place probe on indicated side.Items not to scale.Determine Voltage Wire & Label WiresAt the temperature control, with a volt meter, locate the following wires and mark them as directed below:• Line in/Line; Label wire LINE.• Line out/Load; Label wire LOAD.Remove the mechanical control.4-Wire Fan MotorsFig. 3. Fan motor sticker will be on the evaporator housing.TRUE T-Series or GDM ONLYCheck the unit for a 4-wire evaporator fan motor or a sticker (see fig.3) on the evaporator housing. If present, rewire the fan motor before proceeding. See “Rewiring the 4-Wire EBM Fan Motor” (pg. 15).Probe InstallationMechanical Control Probe InstallationFig. 1. Use a p-clip to secure the probe to the appliance or a cable tie to attach it to a bracket or wire.Unplug the unit or remove the power supply.Remove the existing probes.With the provided mounting hardware (see fig. 1) install the provided black (thermostat) probe in the return air stream (see pg..NOTE: Be sure the black probe does not contact a metal surface; otherwise, it will read surface temperature, instead of return air temperature.On any airflow side of the evaporator coil, locate the horizontal and vertical centers. See fig. 2. Then, push the white (defrost) probe into the center.NOTE: Insert the probe flush with the coil fins. Tuck the coil fins around the probe to help secure it. See fig. 3.Run the probe wires to the temperature control installation location.With the provided 3/16” p-clips or cable ties, secure the probe wires to prevent contact with moving parts.Proceed to “Temperature Control Installation” (pg. 6).Fig. 2.

Indicator light locations.In addition to reading the control indicator light codes [see “Control Indicator Light Codes0Table” (pg. 13)], note the potential solutions below:Check the terminal connections:If the power wires (Live In and Comp) are reversed, the control indicator lights will not light and the compressor will not start. See fig. 1. for light locations.If the probe wires are reversed, the control will not cycle correctly.Check if the black probe is touching metal. If so, the probe is reading surface temperature instead of return air temperature.Table 1.

Black/Blue 6-wire terminal block diagram.TroubleshootingBasic TroubleshootingFig. 1. Indicator light locations.In addition to reading the control indicator light codes [see “Control Indicator Light Codes0Table” (pg. 13)], note the potential solutions below:Check the terminal connections:If the power wires (Live In and Comp) are reversed, the control indicator lights will not light and the compressor will not start. See fig. 1. for light locations.If the probe wires are reversed, the control will not cycle correctly.Check if the black probe is touching metal. If so, the probe is reading surface temperature instead of return air temperature.Table 1.
