Error Codes
Safe Error Codes
A safe error may mean either that a control panel button is pressed without the safe signal being
caught, or a safe signal is caught without any control being pressed.
0 = Safe without command from A1 - for future use
1 = Safe without command from A2 - Foot board
2 = Safe without command from B1 - Room interface
3 = Safe without command from B2 - Siderail
4 = Command without safe from head right siderail – outer control panel
5 = Command without safe from head left siderail – outer control panel
6 = Command without safe from the head right siderail - inner control panel
7 = Command without safe from the head left siderail - inner control panel
8 = Command without safe from the foot board control panel
9 = Command without safe from Room interface
ADC Error Codes
On the AC control board, there is an analog to digital converter (ADC) that measures the board
voltage. The ADC measures three voltages. The error happens when one or more of these voltages
are too low or too high. The lockout LEDs will flash when a voltage error occurs.
10 = 24V is too high. May be caused by the AC line that is too high.
11 = 24V is too low. May be caused by the AC line that is too low, by a module that draws too much
current or by the AC control board (see note 1)
12 = 12V is too high (12V for other modules). There is a problem with the AC control board.
13 = 12V is too low (12V for other modules). May be caused by a module that draws too much
current or by the AC control board (see note 1).
14 = 12 VK is too high (12V for relay). There is a problem with the AC control board.
15 = 12 VK is too low (12V for relay). May be the jumper W1 is absent on AC control board: verify if
jumper W1 is present. May also be caused by a module that draws too much current or by the
AC control board. If there is a problem with the 12VK, there will also be a problem with 12V.
To check if a module draws too much current, unplug each module one after the other to find which
one draws too much current. If unplugging one module solves the problem, then replace the module.
However, if all the modules are removed and the problem still persists, replace the AC control board.
Scale Error Codes
When the scale control board is connected to the network and operational, it can send errors to the
AC control board that will then display the error code. A scale error will cause the Bed Exit LED(s) to
flash.
16 = Tilt chip failure. The tilt chip on the board is faulty.
17 = Scale chip failure. The scale chip on the scale board is faulty.
For errors 16 and 17, try to unplug the bed and wait 5 seconds. Then plug the bed back. If the error
still persists, replace the scale board and recalibrate the bed scale.
18 = Foot left load cell is out of range: load cell may be disconnected, faulty or scale board is faulty.
19 = Head right load cell is out of range: load cell may be disconnected, faulty or scale board is
faulty.
20 = Foot right load cell is out of range: load cell may be disconnected, faulty or scale board is faulty.
