• Board ASR003 is an extension of the radiological system, providing an interface for the col- limator to other system devices with analogical signals. • It operates via CAN BUS with a Ralco proprietary protocol. • The user end features 32 digital inputs, 8 analogue inputs and 10 relay outputs.
Page 148 • Digital inputs are optoisolated to allow connection to devices that supply output control volt- ages (typical range 12-32 V DC). • Supply: 24V DC. • Fuse: n.a. (not supplied by Ralco). Digital and Analogue Inputs Digital Input Since the input signal sometimes comes from a voltage-free contact, the board features a number of pins to which an external supply may be connected.
Page 149 Model R 221 ACS - R 221 ACS DHHS The 10 output relays each have an NO/NC contact and may consequently be adapted to a number of different configurations.

Page 238: Maintenance
ECOMMENDED AINTENANCE ROGRAM Ralco suggests a yearly servicing program, however shorter intervals are advisable when the collimator is subject to heavy workloads. • Re-calibration of the collimator will be necessary whenever the X-ray tube is changed or at each substitution of the source light (lamp or LED, if assembled) used to simulate the light field.
Page 239 Model R 221 ACS - R 221 ACS DHHS • Calibration procedures (if provided) must be performed as described in this manual. • Check once a week that the screws and tabs which serve to secure the collimator to the flange/tube adapter are correctly tightened.
Page 240: General Warranty
In the event the collimator needs to be repaired at Ralco, you will be provided with a RMA (Return Merchandise Authorization) number as your consent to the return. If a product is returned to Ralco without a RMA or without a description of the problem, the customer will incur a €100 processing fee.
Page 241: End Of Life Disposal
Should this prove impossible, return the collimator to Ralco at the purchaser's expense and Ralco will undertake its correct disposal. If you are replacing the unit with new equipment, you may return the old collimator to Ralco. Please contact us if you require further information.
